A friend just upgraded a mod on their server, and got this crash. The server log has a bunch of id mismatches, I thought that was supposed to be taken care of automatically? Or is it something else that's wrong?

Did some searching and couldn't find any other evidence of this being reported.
If there's any mod with child mods installed, every time you view the mods list, it multiplies the count of child mods. Yeah, quite minor.
