Thanks. Taking save.
Done. https://forums.totalwar.org/vb/local...id=199&id=4815
I had a little trouble with the battle because I wiped out the reinforcing army from the city so when the strat map loaded back up I captured it and had the three options. But when I selected one the game crashed (probably because it was in the middle of a turn). I tried it twice, but same result. So I autoresolved, and still won. Then (on the new turn) I assaulted Diospolis Megale and won, so it is now ours.
