Game crashes on load of a save.

[Sanchez-1]

Hi there so basically I'm running the newest KSRSS Reborn and everything works perfect until I installed Principia. This was my log file for the fatal error that closes the game out right on load of a save. (I would have put it on gist but since it was so small I figured pasting it worked aswell). I know it has configs for Principia and I have zero clue what the error means to understand it, any help would be great.

Well, you can bump all you want but you didn't give us the INFO log as instructed by the FAQs so as it stands this bug report is unusable.

This being said this kind of crash has been seen with mods that violate the invariants of KSP and create two parts with the same id. In some cases we have been able to work with the mod author to resolve the issue. The first order of business would be for you to figure out which mod is incompatible with Principia (e.g., by removing them one by one and trying to reproduce the bug).

Can confirm that the issue is produced by Principia, since it doesn't appear when I don't have it instealled. As requested, these are the last FATAL and INFO logs:

@amoraschi, your issue is unrelated to Sanchez’s; your FATAL log has the error

F1120 00:47:01.671447 11384 map_util.hpp:58] Check failed: it != collection.end() Map key not found: 34

whereas Sanchez’s has

F0915 18:27:05.842931 19160 plugin.cpp:1645] Check failed: inserted part_id: 3080220487

Your issue is likely due to changing the solar system on an existing save. Principia does not support that; make a new save if you add bodies to the solar system.

Specifically, the body with flightGlobalsIndex 34 is not found (a cursory GitHub search finds than RSSExpansion assigns that index to 21 Lutetia).

Strange, I'm just using KSRSS Reborn just like Sanchez, I'm not changing the solar system on an existing save and I'm not using RSS (KSRSS does import things from RSS Expansion tho)

Did you mean that to use Principia I need to start a new save?

At this point, yes (this is recommended in the FAQ for a number of other reasons anyway).

The likely scenario here is that at some point you opened the save with Principia installed and without body 34 (which created the Principia save state for a system without body 34), then added whichever mod adds body 34, and opened the save again.

Closing as the OP never provided logs and the second issue was properly resolved.
