Often when you joint a server the PlayerData bugs around. By this I mean you can't leave, are not in any gamemode (no hearts, no creative inventory). Then you have to rejoin. It only happens when you have items from Create in your inventory. Can you please fix this.

This issue has been marked as stale because it has been inactive for 3 weeks. It will be closed if it remains inactive for another 3 weeks.

Is in the new version fixed

can't fix without diagnostic info

Seems like the server is lagging. May you also provide a screenshot of what happens?

The Server was lagging. I Upgrade hin total and it happens too.
