Crash with Principia when clicking "finalize"

[Astavie]

Hi!

Love the mod, but it keeps crashing when I try to finalize a ship. Looking at stderr.log it seems it is incompatible with Principia, maybe? stderr.log

I also have a save file if it helps: default.zip. I installed a few mods but for the vessel on the launchpad only Kerbal Planetary Base Systems, Principia and Extraplanetary Launchpads is needed.

I'm also experiencing this issue. Would like to bump!

I'm not sure whether this is more appropriate on the Principia Github or here, but the relevant log is

It would seem that EPL is not giving the new vessel unique part IDs with respect to the new vessel docked to the launch pad and the rest of the vessel, which causes Principia fail a map insertion.

[taniwha]

EL does not give any IDs to anything: all ID assignment is done by KSP. EL creates the new vessel as a separate vessel then docks it to the parent vessel using KSP's docking code.

I have same symptoms but I do not have Principia installed. So the issue might not be related to Principia. And I belive long time ago I had it installed and I would get that error, so I uninstalled it, and still would get the same game crash problem but without the error. So again it is most likely not Principia. Some more info:

1. This does not happen all the time. My success rate depends on how complex the surrounding is. for example the more parts I have on the station to which construction dock is attached to, the more likely the crash will happen.
2. up until recently I was running the game on KSP 1.4.7 with 6.2.2 of EL, which also had this issue, and one of the that was happening is that the newly spanned parts would span not next to the construction dock but with construction dock inside. So looks like size/displacement calculation was off. I resolved that issue by attaching very long I-beams or girders to it in such a way that I knew that there would be no overlap. That would reduce the chance of freezing by order of magnitude. So instead of crashing something 4 out of 5 times, it would crash only 1 out 5 times.

I think the problem might be with KSP checking for collisions and that is where it dies, since it does not really expect for something appearing out of nowhere, which is what this mod does.

P.S.: So I'm running 1.8.1 KSP right now with 6.7.2 of EL (and a ton of other mods.) and just verified my #2. I un-docked Assembly plant to which I have the construction port attached moved it about 50 meters away form my station, and finalization was successful this time, but before that I tried without undocking, and with undocking but not moving away, other than just drifting a little bit, and both times the game crashed. This really makes me think that it has to do with some kind of collision check. Also it looks like the sizing/displacement calculations are correct on this version of the EL. The spawned parts were position correctly with out any overlap.

Please see if 6.99.1 improves the situation: commits e2e4ed1b75b49c71d176319664d9c3e348ef0086 and d1b10df5497efba44a28e55f7f466c995c4f9e5f seem to me to be highly relevant to this issue.

I have not heard anything for some time, so I'll assume this is sorted out. If not, feel free to reopen the issue or file a new one.
