Actually enemies with move routes never go off their route. NAMK already asked me to change that, I just haven't come around to do so yet.
BTW, v2.21 is up. I'm sorry, Makasu, but I haven't made the running/sneaking sprites work right yet. I need to change parts of the sprite extension system anyway and localize the setup at one position in the coding.
EDIT: Lol, v2.21 is my Christmas present for you guys. xD
