Lately I'm seeing a super weird bug that I've never experienced before, and apparently it only happens in the campaign. You see, the only pattern I have found is when units charge against the enemy, and apparently it is with all units (infantry, cavalry, missiles).
The units stop responding to orders and stay fighting for a long time. I've noticed that when this happens, the attributes interface goes gray, as if the unit is 'locked' or something; I share a screenshot in the attachments. I have stupidly lost units and my general because of this damn bug, which I don't know why it happens. Does anyone know what's happening?
