Some height/Map coordinate calculation for all units

BATTLE.BIN :  - Some height/Map coordinate calculation for all units
Reset AI Table 0xb4c then enable Tile adjacent to an Ally with Monster Skill in AI 0xb4c Table (if delta Height is less than 2)
Bug ? The last loop checking both elevation seems to not doing it. The way the counter is handled seems wrong to me.
