Bit of an exploit. If a block is built next to a downward slope like so:
____/====
__[]/====
And the player stands on top of the block, monsters will come towards the player and stand on the downward slope confused as to what to do next.
o
___[]x/=====
Player ( o )is safe whilst monsters (x) are turret cannon fodder. I suspect the path finding sees the downward slope as the same level of terrain as the blocks upper surface, however collision detection processes these differently and thus the monsters jitter back and forth.
