I'm not sure if it's been fixed in 2.0, but my troops won't follow me through the door if I break down the gate during a siege. They act as if the door is still there blocking them. Anyone else have that problem?
Aha, that's a problem with portcullis pathing. Not much can be done - either remove the door or seal it off completely. Which castle was it?
I've had the problem with several of them. Never had one where it worked, but tbh I've only tried it a few times. Never had one work. Sure would be easier taking the archers out from behind if I had some company.
