Bug Description

When playing Hypixel Bedwars, upon dying and sent into respawning I get kicked for "io.netty.handler.codec.DecoderException: Failed to decode packet 'clientbound/minecraft:boss_event'"

After that, even after rejoining I keep getting kicked for that until im sent back to the lobby/game over.

Steps to Reproduce

Join Hypixel With 1.21 (set to 1.8.9 version)
Join a game of Bedwars
Get Kicked for "boss_event"

Expected Behavior

Continue playing fine and have fun

Can you try the latest dev build? https://ci.viaversion.com/view/Platforms/job/ViaFabricPlus/

One sec ill try dev build

[lowercasebtw]

I think its only occuring on a specific map one second, I'm currently trying to reproduce with my current build

[lowercasebtw]

I do see this upon joining a round of the map "Nebuc"

[FlorianMichael]

anything wrong with that?

Final Note;

I haven't been able to reproduce it again with my current build so I cannot deduce/conclude it happens on either the dev build or not.

The image was the only thing I noticed that is dfiferent than the other maps/games I have played on which could be a reason its happening. This bossbar shouldnt even be showing anyways as it doesnt show on vanilla 1.8.9.

Will come back later on when I can reproduce it or find more info
