You know, I think that the way that PD is handled may actually be implicated in the commander/unit limit problems. The units and commanders in PD are generated anew every time a battle happens, so many battles, with high PD, could hasten the descent into such problems. Just a thought, I'm not 100% sure how the game handles it, but they are created out of thin air at the onset of battle, and they must have IDs of some kind.....
