Thanks, I made some updates. RE the terrain quality switch, what kind of graphics card do you have? I'd like to mention it when I post it.
RE diplomacy, is that how the test says it's supposed to work? Because it if it was, then you'd only be able to use it when you're armies were less than full (and I don't know about you, I'm always "full" if possible). Seems to me if it's working as intended then what you're supposed to do is visit a garrison before the next combat so you can save the extra troops. I suppose they could at least go into open/eligible reinforcement slots. Anyway, not sure if this is a bug vs. working as intended. Perhaps add to the
suggestions thread?
