About the Great Tactical AI...
Two things:
a) for each new battle, AI builds a new tactical plan (TP); generally speaking, the TP are very different at each time but that is depending on the kind of maps... Wavre is a bit complex because there is a river in the middle of the map and AI doesn't like the rivers
Consequence : could you try to relaunch the battle; it is possible the Tactical Plan could be better.
b) after finishing the new GUI, I'll work a lot of this AI; I think the next version will be improved a lot. In the present one, the reactivity is very low; it is able to take the advantage when it begins to win, otherwise it isn't very efficient.
Clear?
