On station15, I moved human base to the furnace room. But human bots seemed to be going the long way via human default or the garden, instead of the other door, which is much closer to the alien base.
On nano, a basilisk was stuck on a wall in middle area, trying frantically to get at the telenode behind the wall. When the node was destroyed, the basilisk stopped moving. A couple of human bots somehow got stuck in a gap between the reactor and the wall and couldn't get out.
On cruz-b6, all of the human bots were stuck on the conveyor belt, and consequently, all of the aliens were stuck at Bob's Boulevard, above the conveyor belt. I built a few eggs closer to the human base and team killed some of the aliens so they can spawn else where but it didn't stop them from hanging around Bob's Boulevard.
On methane, I built eggs on the ceiling at the end of spill way. Dretches started to spawn and got stuck on the corner of small ledge, and soon, there were four dretches on top of each other, unable to move. I couldn't push them off and goon barbs didn't dislodge them from the corner either. Also, a tyrant was doing bad things to a tree. 
On spacetracks, I tried to push the tyrants into the elevator but they wouldn't go in. On same map, different game. I built an armory at the stairs. Three tyrants came up the stairs but got stuck. I was expecting the tyrants to destroy the arm but they didn't. They were just trying to push their way into the gap between the arm and the railing.
On ATCSHD, all the bots were stuck in their base.
On most of the maps, the bots seem to be using only one route into the enemy base, even when there are shorter routes available. Also on multi-level maps, bots have hard time getting to the enemy base. They just go about half way and then return to their base. Otherwise, they are very vicious and difficult to kill when they are in groups.
