I have a couple mob farms set up. They work fine until skeletons or zombies start getting partially stuck into blocks. Once this happens the game will lock up and crash.

It's not just skeletons and zombies that are causing this, but also other entities such as armor stands. I was using version 1.12 but switched to 1.13.0.2 to see if it would fix it but it hasn't.

This also happens on the Switch, and I reckon that it happens on Windows 10 as well.
