I just noticed this after patching to 1.54.
I'm in a squad that has about 4 AI soldiers. I gave them a waypoint and set the mode to combat. At the beginning of the mission, the AI units just run into cover and NEVER move again. Before they would move from cover to cover until they reach the destination, but now they just run to the nearest cover and stay there until they get killed.
Anyone else noticed this?
EDIT: Same thing happens in stealth mode.
EDIT2: This also happens if I'm not in the squad, so it doesn't have anything to do with the player.
