Error: Cannot invoke "net.minecraft.server.level.WorldServer.v()" because "world" is null

[ofunny]

I get the following error on my lobby server whenever a player leaves the server. (For some reason it does only appear on the lobby server and not on any of my other servers. The lobby server has no extra plugins what are not also available on the other servers so it may be related to the server setup itself but I could no figure it out).

` MySQL Player Data Bridge 4.2.0 Paper 1.18.2 #252

Would be nice if you could fix it. I use "MySQL Player Data Bridge" for economy sync only – otherwise I have to move on to another plugin since is not the first problem now and the support is actually dead …

Yeah, I'm having exactly the same problem

Same issue here. It seems to come from the world name. I have the plugin on 4 Server and on 3 of them i become the error. The 3 with the error don't have a world named world. so maybe that is the problem

My worlds are all just named world, so that can't be the issue.

I have the same issue.

Fixed in version 4.4.0 and up
