Oh, that's so nice! Thank you for that change, I always disliked how autopathing moved me through collapsed tiles, especially when moving long distances.
I'm surprised i didn't notice the auto-avoidance in my first Beta 13 run. Habit of segmenting mouse movements to avoid pathing through collapsed tiles, i suppose. (I mean i did notice it, but only in the very last area, so i thought it was a special case...)
