[net.minecraft.server.network.ServerLoginPacketListenerImpl/]: Couldn't place player in world

[5apphy]

I own a server which I use to host modded minecraft servers on, and for about a year, I've had no issues whatsoever, but about a week ago, whenever I try to join any server I load, the logs say that they can't find anywhere to place someone in the world and..Well, I don't know, the server itself runs perfectly from what I know, but no one can log in. I can't find anything about this issue, which is most definitely fault. We primarily play on 1.18.2 forge, with a bunch of mods

This is the..at least what I think is the relevant part of the log..

I'm sorry if I'm being an idiot, but if someone knows what I need to do, that'd be really helpful!

Same issue without epicfight?
