[1.7.2] Disengage can teleport through walls

[Horken]

In certain situations it is possible to disengage through or even into walls. If the situation is like this: m@_#_,
with m some monster, and # a wall, then the visual targeting will turn red at the wall, but if you nevertheless click on the space behind the wall you will be teleported there. Can also happen by accident if you are blinded and don't know the terrain you target.
