So yeah it seems that major battles freeze up. I had a stack of 700k men face 500k enemies (goddamn frog eaters) and even after like 3 years, nothing had changed. I still had about a 65% advantage in the battle, that's it. Really annoying since this was a large portion of my army, tied up and unusable forever.
This was in like 1881 or so
