Hello, 

I'm about 225 turns into my first game. An enemy besieged one of my largest cities and immediately engaged my weak garrison in Battle. I was able to survive the attack and the enemy army retreated, but my city was still under siege, even after the enemy left the region. I chased the enemy down with a reinforcement army and eliminated it, but the barricades from the siege remains with my troops and hero trapped inside. There are no enemies in the region. I have since captured surrounding enemy regions, but it didn't help. I brought in another army inside the barricade, but now they are trapped, too. I have restarted the game, but that did not help. I even considered going to a previous save file, but my auto saves won't take me back to the point before the siege and the next available file is about 40 turns earlier. I can't think of anything else and I have not come across anyone else on the internet encountering this issue.
