Error on opening some pawn gizmos

[KoenLemmen]

After the latest update on the workshop I get the following on some pawns, it's rare, but it happens.

Short error:

System.NullReferenceException: Object reference not set to an instance of an object

In the error I see 3 transpilers, so I also ran the game in various configurations without AllowTool, PerformanceOptimizer, and Blueprints (forked, not the original one) but the error persisted.

Looking at the commits I think it might be because of the recent commit https://github.com/Vanilla-Expanded/VanillaExpandedFramework/commit/6ddbdf2030fc0a868583507fd253b5472d665a64 because I haven't seen this error before and the changed method is the one in the error.

The game is very modded, so it may very well be something in my game, however due to the recent emergence of this bug and the latest commit, I think they might be related. Here are the full logs: https://gist.github.com/HugsLibRecordKeeper/4ca1be65797de9181a9607afdc8891b1

Thanks.

I tested it with the previous MVCF.dll and the bug is not present one commit ago.

Thanks, will null check to avoid this

Is there a way to use an old version when using steam workshop?

[KoenLemmen]

Thanks, seems to be fixed
