Hey, me and my friend can't join eachother after installed this mod :( is there any fix for that?

What does the error say when you try to join? Are you sure that both the server and the client have this mod installed?

Hello, i found out that it only happen with some other mods installed, everything's fine after uninstalled them :D btw the error said "Internal server error", thanks for making this awesome mod!

btw sorry for my terrible english!
