Opening a map kicks the client from server. This does not occur in singleplayer.

I will provide server.log
server_log.txt

the client.log only provides this [INFO] not sure if useful

In version 1.17.1-1.10.1 this issue has been fixed!

Thank you

odd that it didn't cause issue in 1.16. Well not exactly sure if this got fixed but I just published a new version that might work. Didn't have time to properly test this today but if it doesn't I'll publish another quick patch
