Loss of probes after decoupling. Since 1.11.

[Danger2007]

Hello,

I'm in a bit of situation after the new update. I have several probes which have small lander probes attached to them. When I decouple the lander all control is lost, and its orbit speed it set to zero, with a time to AP of infinity. I can switch to the lander straight after I decouple, but if I go to the tracking station or something the name is either not listed or listed but I can't switch to it. I have a probe core on the lander, and when I switch to the craft it allows me to rename and things, but it doesn't respond to inputs.  It has a full strength connection to the space centre.  I have several craft all of the same design and they behave the same way - anything that's decoupled is bugged. They worked just fine before the update.

From a coding perspective, it seems when I decouple the "new" craft that's created is bugged. 

I'm running a mildly modded install - It's most of Nertea's stockalike parts (which are great), kerbal engineer redux, kdex, and the MS3000 mini materials bay. As far as I know none of these are particularly heavy.  All of these are uptodate I believe, I just went through and reinstalled the latest files this evening, and they were all marked as 1.5.1 (the other update/patch number?)

[EDIT} I've just tried launching a new craft of the same type and the issue persists, making it potentially save breaking.... 

Any ideas what could be causing this?? Apologies if there is a thread somewhere else with similar issues.

Thanks in advance!

This feels like the game turns your mini probes to Debris.

Do you have Max persistent Debris set to 0 in options?

I am just dropping a random idea but i think for some reason it categorizes it as debris and you need to change that to probe or whatever.

I had the same issue. Several crafts I launches with probes attached by decouplers seemed to break when I tried decoupling them. I could switch to the new probe, but it would read a velocity of 0m/s and if I went to the tracking station the new probe would vanish and wouldn't be in the tracking station or near the parent vessel.

Launching an old craft file with the same design caused the same issue to happen.

However, if I edited the craft in the VAB, removed the decouplers and attached probes, and then reattached them, the newly launched vehicle behaved properly.

Not much of a solution for your existing craft but this should fix new craft you want to launch.

Check the vessel naming configuration by right clicking the little lander’s probe core, it’s in a drop down menu (don’t just rename the vessel as that affects the whole thing). Set the lander to be a lander with a priority of 9- the default is 10 so this should avoid overriding the main probe’s name- and then decouple and see if it works.

Does the same thing happen using a different craft with a similar design? Could be a broken craft file, try rebuilding from scratch and see if the issue persists.

Hi, thanks for the responses! I tried them all at once, so I'm not exactly sure which worked, but I'm back in business!

Thanks again.
