I have been noticing that these guys seem to get stuck on one block wide ledges a lot. The main issue with this is that when you go to fight them, because they are glitch/stuck or whatever you end up getting reduced rewards or nothing at all. I have tried to knock them off those ledges to flat ground, but often that doesn't work. Also if they are anywhere near trees then there doesn't seem to be any way to fix that do you end up losing out on rewards for killing them. Is this something that is due to their size and how the game sees them or what?
