[Suggestion] Fix Rats AI

[SaltSouls]

If at all possible, assuming you guys are still working on these, would it be possible for you guys to fix the broken rat AI in 1.12.2.
By this I mean that rats will get stuck trying to do a task and won't quit, even if it is unreachable. Their wander AI is completely broken, causing them to just stand still, and wild rats struggle to jump up blocks to get away from the player. Rats in a cage will not wander around like they are supposed to, and will instead stand completely still(thus making big cages and tubes entirely useless).
