Describe the false positive and how to replicate it

When the player respawns, Grim think the ground is air.

ManInMyVan commented 2 months ago

Does this happen on the latest commit? (2.3.64 isn't latest anymore)

Anonymous-Dragon commented 2 months ago

I can test it out for you but I don't know how to compile/turn into jar file from the last commit. sorry

matsu1213 commented 2 months ago

This did not happen before.

That line is correct, the player entity is recreated. It wouldn't cause the offsets you are seeing.
