I ranked up, developed my army, and now I'm mixing following my faction commander with independently crushing enemy parties. The problem is, nothing is progressing. At all. My faction commander will siege a place, wait around for 2-3 weeks, then bail on the siege to go siege something, or he'll just stand in one spot and, when asked, will reply something along the lines of "I'm considering my next move."

As far as I can tell, none of the factions have successfully sieged or taken anything. They just run around, alternating wins and losses, and nothing ever happens. This mod is weird because, unlike virtually all other mods, I don't see a way to personally siege/take anything.

How can I actually progress the game along so it doesn't feel so interminably grindy and pointless?
