Also your Forge version is really outdated. The latest one is not 1291, but 10.13.4.1614! Though you should stay at a version level compatible with your server software if you use Cauldron or KCauldron.

You should post your server log somewhere (pastebin) for reviewing. Good to know (illegal prefix errors being irrelevant).

I tried both 10.13.4.1614 and 1291, but neither fix the error. Believe me, I pratically burned the entire day just trying to figure out this problem. Even generating an entirely new server, testing different combinations of mods, different Forge versions, and different world saves. The only thing that produced a result was the change in world save.

I will post the server log, because at this point I'm out of ideas, and I figure someone out there (like you) might be able to offer a second pair of eyes. Besides the larger influx of illegal prefix errors, I didn't really notice anything peculiar in the sever log, but here it is anyway.
