Not sure about you guys but at least once during every match I have a situation where my entire squad stays behind and get wiped out after using this command form the wheel. It usually happens when we lose a sector and have to fall back.
VERY frustrating.
Sometimes they get caughed up in fighting so i usually set them in passive mode but theres other times they also get stuck
As @34503810 said… They are mostly likely caught in battle and just trying to fight.
If you need your AI to follow you until they get directly fired upon, you need to set them to passive mode.
Of course, poorly placed rallies are also causing AI to get stuck (such as rallies in basement or wagons etc).
