I was afk farming at my iron farm and realized that one of the golem that spawned got stucked in a water current, while he should've been pushed by it.

This only happens sometimes but it happened to me more than once, idk what may cause this problem.

I have attached a screenshot of the problem. You can see that the water is not static, it's pushing the golem to the lava, but he gets stucked there. He didn't spawned there either, he fell off the upper water current.
