My siege has been stuck at 8% for a couple years, despite having an army larger than the (pretty large - level 4 I think) castle I am besieging. Is this a bug, or just going really slowly? I have about 5000 men, they have 3250 or so in the garrison at the start - don't remember exactly because I tried a foolish assault.
How many of those 5000 are infantry/ashigaru?
