I've noticed my units have a habit of getting stuck at points. For example in GC on Bothawai, Yoda was destroying a Consortium bunker but after destroying it, would not move. He was stuck in that spot. Then last night the same thing happened in Skirmish on Felucia. The water by the imperial base, Obi-Wan got stuck. Luckily I was able to land a gallofree near him and airlift him out. But then yoda did the same thing, and I mistakenly sent in Garm and they BOTH got stuck.
This happened in EAW as well when Vader was by a buildpad.
