On installing the patch It creates a new folder in Program files named- "TheProtectors"
while the original game folder is "The Protectors".
So it requires manually copying the files to the game folder.
And some bugs I found earlier-
-While selecting a race for an AI, Fey race appears twice at the bottom and then after that "Random". If we select random from here. It appears as X. And then the game crashes after retinue screen.
-Right clicking on the Hero portrait used to bring up the strength, intelligence etc of the hero, and then the different skills points of the hero in WBC3. but in the mod rt click does nothing.
-AI seems to be bugged. In one game none of the enemies were converting any mines. their generals just stood there near each mine. And in another 2 of the enemies destroyed one of their base mine at the starting of the game, instead of converting it.
Also in most games the races will build and stack useless units. like knights will build lots of peasants, and keep them standing in the base. some other race was producing lots of eagles from their keep, and not using them.
