Just wanted to add, that yea, thats a problem, some variations of "stuck" are very often for me, not only that even worse is when character instead of going somewhere "tries" to get there so he constantly runs up and down a path ,blocking other in the result, this happens not only when the road to the waypoint had blocked, but even when its "tight" fit (i CAN manually direct him there).Not only that, enemies get stuck also, and they cant get unstuck, My friend had a situation where one of the main bossess (at the end of paths of damned..) got stuck and did nothing whole battle, so was easily defended :-/.Collision system seems to be not that great, another example, in dungeons, there was a big hole in a wall, i could get through it with two characters standing beside each other, however , when i strategically put a mage there and tried to shoot fireballs, they got deflected by nothing and i was shooting at myself, whats even weirder is that sometimes it got through at weird angles :-/.Its all down to unity probably .And going to be a tough fix.
