Line of shot (MOBS) BUG

I saw multiple times ranged type of mobs trying to shot out of the corner when they are unnabe to land hit.
M- mob
P- player
c- corner
- wall


P


--------c c----

M

I dont know is it important to repair it, but it was easy to use it as exploit.

2 options i see:
-make mobs move far above the corner.
-make ghost corners.

Ok back to play!
