Monsters not in location shown

It's related to pathing - Some monsters will find a way past something on the client, but not the server, or vice versa. We do have plans to fix this, but it is more noticeable with some play styles than others.

Sadly, there isn't an easy solution - It requires restructuring of the way the client and server communicates. We've learned a lot since we did this last time, so it'll definitely be an improvement this time!
