I'm not sure how to describe it but ever since I upgraded to 1.13.5 I am getting NAN floating point errors in console, as soon as I reload my quick save my altitude goes to 000000 and my ship disappears,electric charge value is NAN /2420 and thermal power and mega joules are 0.00/0.00, reverting tracking station the ship reads as being on escape trajectory out of the sun, planets disappear, clicking on other ships shows nothing. also my probe has the "candle" engine on it

Hi every one, in the console i get some error related to KSPI :

"did not get techic advEMsystem"

and

"did not get technic ionpropulsion"

Is this normal ?

Could you describe how to reproduce?

Sovietsanta · May 13, 2017

I simply updated from 1.13.3 or 1.13.4 mid game and loaded my save up and it immediately happened when I went back to my probe, also I had a probe of the exact same design arround duna that had the same issue, I think it has to do with the change between versions to the candle engine I ended up having to re load a backup then remove all probes with the candle engine from the persistent.sfs, which ultimately fixed the issue because before even relaunching a separate new probe with the candle caused the issue to happen to the new probe at the launch pad with the ships that existed with the candle before the update. I am not to sure how to reproduce other than trying the update process mid flight from one of those older versions to 1.13.5 with a probe with that engine. Maybe it was an isolated issue I'm not really sure

ss8913 · May 13, 2017

@FreeThinker - new update has done a few things for sure, maybe 1 other thing:

1. Framerates are a lot better. Not sure why, but they are.
2. This was mentioned on the other forum - electric charge bug. Electric generators stop generating electric charge after any dock/undock operation. F5/F9 save/reload fixes it, but this is definitely a new bug.
3. (this was 2 updates ago) - Umbrella radiators no longer deploy automatically in automated mode. have to deploy them manually now in all cases.
4. The game is... very crashy. After the EC bug is hit, that F5/F9, about 25% of the time will crash KSP completely - this is the one that I'm not 100% sure is a KSPIE issue - the logs are no help, just normal normal normal <<CRASH>> with no evidence pointing a finger at *any* specific mod.

I'm currenty hanging on this everytime i try and start the game with your mod. Any ideas?

These are the mods i currently have installed.

You'll want to look at your ksp.log and see what it says near the end. Probably will want to post it and make it available to FreeThinker too, or he (or anyone) will likely not be able to help.

Ahem, to explode at will?

Yes, don't accidentally push the button. Could be useful if you are afraid of running into kerbin/earth, or to clean up everything in the neighborhood.

You know this is a standard tvtrope right?

MMmm weaponized antimatter.

How close to exploding antimatter tank I could float in space assuming effectively 1 g of antimatter-matter mix will be converted to energy during explosion?

That equals 90 TJ of total energy. Lets say reaction lasts one microsecond - this means total power of explosion is 90 000 TW.

Joebwan · May 14, 2017

I'm not sure if anyone else is seeing this behavior, but when I use the Direct Cycle Nuclear Turbojet engine, the temperature continues to rise indefinitely and results in exploding the engine. I can get this to happen just by sitting on the runway at about 1% throttle. If I up the max temperature in the config file (to something like 1 million degrees k), it can watch the engine temp just rise and rise -- essentially without limit. The nuclear core temp looks normal, just the part temp rises.

0.625m antimatter reactor and same sized thermal ramjet can generate 1.5 MN of thrust!

This is totally not OP ;^)

Lol, it should not be able to draw more than 5% power. Seems I overlooked something

Ok, now it's clear. I supposed (wrongly) that they will randomly explode, lol.

Ando no, I wasn't aware of that site. It seems interesting.

Seems like there may be a mass/size scaling problem with the antimatter reactors and (at least) the plasma nozzles.

To illustrate:

Create a simple craft with a 3.75m antimatter reactor and a 3.75m plasma nozzle. Note the observed max acceleration using MJ/KER. Now scale these up to 5m using the same propellant; the acceleration goes DOWN, since the scale of the 3.75m antimatter reactor to the 5.0m adds so much weight that it cannot compensate for the additional thrust. @FreeThinker is th is intentional?

Nansuchao · May 14, 2017

Just updated to the last version of KSPI-E. This SSTO worked flawlessy until few days ago. In the video the Kraken was awaked every time I activate the TORY by AG. Am I the only one with this issue? This was the third try. The logs show nothing at all, until the kraken is summoned.

@FreeThinker - latest update has broken cooling almost 100%. I can't get more than a couple of seconds of thrust out of *anything* in atmosphere without an overheat. I know you said you were going to reduce atmospheric effectiveness of graphene radiators, but:

1. I thought you did this 2 updates ago and it wasn't going to get more nerfed(?)
2. There is no titanium radiator comparable to any of the graphene radiators
3. There's no amount of radiators that can physically fit on any of my craft that will even come close to cooling the system enough to even get 5000 meters up in the air...

Help? Am I doing something wrong or is something badly broken?

Have you tried the stock radiators, They count as titanium radiators for KSPI-E

haven't, but I may... still, I went from a perfectly good set of usable, flyable craft (SSTO mostly), to 100% useless from last patch to this one. Can't even get halfway to takeoff speed before everything overheats and shuts down. Was a serious drastic change to cooling behavior on graphene radiators in atmosphere; if you could take a look and make sure it's working as intended, I'd appreciate it, since I'm not sure this is the effect that you were going for

I have not made any changes to wasteheat in particular since the last release. What has changed is the amount of power Antimatter reactor produces from which you can only use 5% for electric power, the remaining 95%of thermal heat should become wasteheat. Now this should not be a problem unless you use the magnetic nozzle. obviously this is not the case, which I wil fix ASAP.

For the moment I have degraded the 1.13.6 release to a beta.

Could you send me the your test/play vessels, it allows me to get a better understanding of the problems you are facing

I'll get some examples... I think I can make a simple craft to illustrate the problem using only stock + KSPIE parts, which is likely what you'd need since most of my craft use parts from several sources.

If you want something quicker than I can provide, capsule -> 3.75m antimatter tank (tweakscaled large) -> 3.75m hydrazine tank -> 3.75m charged particle generator -> 3.75m antimatter reactor -> 3.75m thermal launch nozzle or thermal ramjet in closed-cycle mode.
Put 4-8 "winged edge radiator - med" radially attached to the tank. RCS optional. Launch it and watch the wasteheat.

ss8913 · May 16, 2017

OK, @FreeThinker - here is a craft file using only stock + KSPIE parts which illustrates the problem: https://www.dropbox.com/s/uuyohyb7oy0p1t3/TEST-wasteheat.craft?dl=0

Fairly spectacularly. gives less than 2 seconds of thrust before it overheats and fails, and this/similar craft worked fine in the last version. Also, the MJ max thrust calculations are... a bit off. this is a fairly high thrust design, but I don't think it's capable of 50+G of acceleration(?) as the screenshot shows. I'm linking 2 screenshots, one in the VAB showing the dV calc, and the other showing overheat on the launchpad before I even had time to release the docking clamps:
