Georgian Hammer Push 12-1 npc pathing bug

Found a bit of an annoying bug on Push 12-1 for Georgian Hammer campaign. The two objective groups are code named Ram and Giant. Ram makes it to his final objective waypoint. However, Giant seems to run into a pathing issue and units just start to circle a building over and over and over again.

Tried the mission 2x. First time I think I waited an hour (Went for supper while waiting). Second time I increased the time scale and turned on F10 viewing so I could see what was taking so long and recorded a short video of the pathing issue.

This bug prevents mission completion. Tried to fix it myself by moving the waypoints so Giant doesn't try to drive through buildings, however the game won't let me save the mission.

Having exactly the same problem. Giant circling over some buildings. Also waited over an hour. no dice. Tried 3x. Visited the forum to report it and found this post.
