ERROR: Couldn't place player in world

Shiroiame-Kusu commented 5 months ago

Expected behavior

Players can join the server normally.

Observed/Actual behavior

Players cannot join the server.

Steps/models to reproduce

I dont know how to reproduce this problems exactly because this bug is always existing and all the players cannot join the server at all. If you need further information just contact me and I'll try again.

Shiroiame-Kusu commented 5 months ago

I saw the com.comphenix.protocol in the error stack so I wonder is this a bug that related to multipaper or Protocollib?

PureGero commented 5 months ago

Try removing each plugin one by one until it starts working (except for Protocollib). This will let us figure out which plugin is causing the issue.

Also, try testing if this issue occurs with paper 1.20.1 as well.

I have tested every plugins for a while. I cant reproduce this issue on Paper 1.20.1, and everything runs normally after removing GrimAC BUT, I can join and play normally in a MultiPaper server which is only installed GrimAC.

So I made more tests, and finally found that

if I enable GrimAC and Citizens at the same time, this issue will come out.
