It doesn't because the server gets no errors. The server runs perfectly fine. The console shows the standard startup and such, notes when I log in, and when I get disconnected. That's it. I can post the console log if you want, but there's no info there that I can see.
Log is too long to post the whole thing, but here's the end of it. Everything before is just the mods being loaded and there are no errors at all.
