to be fair, mods can not affect the AI in such way for it get stuck in PA. At least not for now. But you both can't know that.
Obviously mods can cause issues.. I just wanted to show that there are problems with this "release" with pathfinding and the AI/performance
If you play Skirmish. For some reason in GW the AI is downright brutal. But in the 1 skirmish I played I experienced the above problem.
And playing without that balance mod is not an option. As you say, the ranges are too short. Balance mod boosts ranges. It does not affect any AI related functions of the ai cmd (the way mods work in this you can't do that anyway, only when offline play is available can mods
overwrite fundamental AI functions).
Part of the reason I mentioned PA pathfinding issues is because I saw how it works correctly in Sup Com 2 just a few minutes previously
