Hello.

I had a similar error reported a while ago, but I'm unable to pinpoint it... Do you have any mods enabled?

The "setRidingState" happened when I having some mods enable, but the other errors happened when I disabled all mods, but in a started map.

Ok, now I tested the error on a new world and it don't happen, so probably the error is caused by some mod

Ok, now I tested the bug on a new world using mods and it doesn't happen, so my world is probably corrupted (?)
