Godlander

please find attached the crash report and a resource pack that can induce the crash upon pressing F3+S

Please see attached video:

This seems to be caused by byte accuracy. The rotation increments client side in steps of 1.4 degrees. 1/256*360 = 1.40625

in 1.13 the log does output something

I found the problem, it's with one of my models.
However the fact that 1.14 snapshots don't log anything and just freezes the game is still an issue.

affects every version from 1.13 snapshots to 19w06 1.14 snapshot

Is it a dupe? that issue seems to be about being able to use the eye of ender when you shouldn't be able to. My issue is the opposite, you can't use the eye of ender when you should be able to.

I generated a superflat world with strongholds in 1.12, was able to use /locate or eye of ender, then opened the world in 1.13. Minecraft still can't find the structure.

Also noticed that the "owner" tag for arrows isn't stored in nbt like snowballs or eggs. Not sure if that's intentional.

Attached a world where this consistently happens for me, tried in 18w22, 18w21, and 18w16. All resulted in crash
