Player heads cause kicks with no errors #9773

Closed SuperPou1 closed 1 year ago

SuperPou1 commented 1 year ago

Expected behavior

Player heads should not kick a player in any way.

Observed/Actual behavior

If i get myself a player head with a SkullOwner, nothing happens at first, but when i open my inventory up, i get kicked out for the reason "Disconnected", both on the client and the server console. Interacting with the player head in any other way has a high chance of kicking too.

Steps/models to reproduce

Give myself a player head with a SkullOwner, for example /minecraft:give @p minecraft:player_head{SkullOwner:"SuperPou"} Open inventory Gets kicked out with the kick reason being simply "Disconnected" with no errors anywhere

I have found some really old player head on my server with a skin, but it doesn't cause any issues with kicks, and also its name is "Player head" instead of (name)'s head

Can't replicate on a clean test server with a vanilla client. Should try testing without any plugins and with a default vanilla client (which is a good practice for bug reports in general) and see if that fixes it. If it does, then this is likely an issue with one of your plugins / a custom client (if any).

yeah, it seems like it is an issue with some plugin i have, because i tried deleting all plugins and the issue disappeared
