In (pagan) mission 4 the unit warping got so severe that I had to use this tip to get rid of it. Unfortunately because of that the music stopped playing altogether, but I also noticed that the supply wagon is not replenishing ammo anymore, neither for archers nor mangonels.

Has anyone else run into this issue? I'm starting to feel glad I bought this game during a sale, I was hoping for a pleasant nostalgia trip but it's just too freaking buggy.
