--depends on your map logic, just make sure u always clear units u wont need anymore in the map from ALL_UNITS table, hooking RemoveUnit native
--also clearing decayed units which can be done for example through catching death event and wait for UNIT_RF_DEATH_TIME + decay_time from gameplay constants until clearing that unit as well
-- in my project i am always removing units manualy when they are not needed anymore so just hooking RemoveUnit will do the trick for me
