Latexes wearing elytras can get stuck on blocks, which can cause a crash.

[bijimio]

If a latex player with an elytra crashes into a corner they may become stuck, and the player's legs and arms will disappear, if they try to use a firework to escape the situation, it can cause the game to freeze and crash.

the crash caused by this has a non zero exit value.

Can you see if you can find the crash log for this? A non-zero exit value only indicates the program exited with a failure. It would be in run/logs/.

So, I was able to reproduce this glitch, no crash log as the crash was caused by the game locking up completely, but the server does spam
[Server thread/ERROR] [minecraft/Util]: Invalid entity rotation: NaN, discarding.
inside the console

It also seems to be reliant on some forms specifically, I had an issue with the taur form, but the squid dog form I never had it happen once.

Error appears to be from a NaN delta movement value, unsure if this bug is specific from the changed hitboxes?

[LtxProgrammer]

The bug seems to happen when a player with elytra glides down in a corner perfectly negating gravity. Their movement speed is perfectly 0, and LatexVariantInstance.multiplyMotion() never assumed such a case could happen.
