I can't launch a server with only the specified version of touhoulittlemaid installed at all. It's loading client only classes on the server.

In your stack trace, railcraft appears to be doing something with fluids, which is triggering touhoulittlemaid to do something with a spell card that crashes when it tries to access the client proxy. This appears to have been fixed in this commit: TartaricAcid/TouhouLittleMaid@2073508

I don't see why you think this is an issue with JEID. There is nothing here that indicates that is the case.

Oh, you closed it. Okay, guess you figured it out.
