I vaguely remember "Physics Easing" being introduced not just for Ground Bases but many vehicles breaking or exploding on sharp introduction of Physics.  Feels at least half a kluge and avoiding fixing the real root cause(s).

I don't know if the root cause has a solution. IIRC, the problem is the low precision  of the floats used on the physics engine. As you distance yourself from the craft, the lack of precision of the floats starts to kick, and on one of these unavoidable roundings your collider would unduly hit another collider and then… BADA-BOOM….

When you had to add or increment the float's exponent, you lose an entire order of magnitude of the available precision. More than enough to make touching colliders to "invade" each others space and trigger a catastrophic event.

I'm getting weird behaviour when trying to use airpark on a vehicle that has a hooligan airships envelope on it,

Firstly the vessels doesn't stop moving,

Secondly, when i press airpark again the vessel is pushed by a phantom force that increases it's speed significantly (I can reach 3000m/s at sea level sometimes)

Yep, happens to me too at anything beyond 140m above sea level

I've been having some pretty unusual behavior with airpark - if I park an airship, then fly an aircraft to it, the airship teleports into the aicraft, destroying both. Using KSP 1.10 & RSS/RO

No logs, no support. And a video showing it would also help

Apologies, let me get a fresh log with just the incident...

Initially tested on 1.7.1.4 , then tested with 1.7.1.7. Initial incident would merely teleport the airship fully intact, and the collision between aircraft and airship would cause damage. In the logged tests below, the teleportation kraken-destroys the airship outright.

That is curious.  Looks like it happens when you get into physics range.

I'll take a look, but it's not going to be right away.

However, you are using a few mods which might impact it, FAR, SSTU, CameraTools and InfernalRobotics.

And I'm seeing some very odd exceptions in the log file.

I'm going to ask you to do the following:

1. Make a new install, only install AirPark and it's dependencies
2. Make a totally stock vessel as your carrier. Put something on it to lift it up, doesn't have to be strong
3. First test, just put the carrier out on the launch pad.
4. Enable the Cheat Gravity, then lift the carrier up into the air, about 5000m high
5. Park it
6. Restore Gravity
7. Launch a plane
8. Repeat the same tests you did above

This will demonstrate if it's any other mods interacting with it.

If it still fails, then send me the craft files you used so I can test the same scenario.

Honestly, thought it was definitely a mod interaction. But, seems to be a fault of AirPark itself. 

 

I completed testing on both 1.10 and 1.12 with the same result. I've included the example "airship" but even the most basic craft is sufficient.

Ok, thanks for looking.  I will look into it, this will be very helpful

Were you able to make any progress on the issue? If not, that's fine -  I know you maintain a lot of mods, and I thank you for it

I made some progress, but not enough, unfortunately

Oh dear  

I have been testing, and the air parked vessel does indeed teleport directly onto the active vessels location,

I thought it could be related to planetary rotation, so I tried positioning ships at the north and south pole of Kerbin (used Hyper edit for speed and frequency), the teleport still happened...

Not sure if this helps much though

@linuxgurugamerI have this issue where I use VesselMover to move a craft up into the air and then park it (for a ksp movie). For some reason, the whole craft swings upon switching to another craft/ going eva. Any way to fix this?

Any updates on the teleporting problem?

Well, you have two mods which are probably interfering with each other.  Try setting gravity to 0, release it in the air before you park

I'll try that, thanks for offering a solution

[Derpistheword]

Still nothing?

Please correct me if I'm wrong, but as far as I tested you can't persist the Landed state in Jool's atmosphere (or any other planet without PQS). Am I right?
I tried both this awesome mod and the technique I learnt from Stratzenblitz and HoDeok: gain the Landed state from Vall with a glitch and then transfer to Jool being Landed. Then slow down to 0.3m/s and go to KSC or quicksave.

Well, you can go back to KSC and quicksave, but when you switch back to the craft or F9 it breaks: although it is intact, you can't control the craft, can't change camera, etc.
The log gets spammed with NPEs (and the stacktrace points at the GoOffRails method).
