This problem only affects mechs, right?

Yes

Yeah, I'm not sure how to fix this right now. Since it's working fine for pawns, iunno why it doesn't like Mechs. I'm guessing the assemblies need updating or something, but unfortunately I'm not the original author, and iunno the C+ stuff.

I'll look into what I can do, but probably really just need to find a C+ dude to fix the assemblies :S

EDIT - I've looked into this, but since iunno C+ at all, I'm not having an easy time of it. I can't find any reason why it would only have issues with Mechs. If anyone knows how to fix this, lemme know D:

EDIT - This problem has been fixed thanks to the efforts of Robfal2 who rebuilt the assembly files. ^^
