Skeletal warrior count when using last grasp on them

when using a scepter the first 2 skeletal warriors have no base spirit count, how ever if you increase the count and have Last Grasp support gem equipped on them, the the 2 that are allocated as free minions die those 2 stop respawning and the count goes down by 2 or 1 in the game UI but stays the same in the skill panel UI. It does not happen on the first set of deaths but does happen often. fix to this is either stop using Last Grasp support gem on them and they spawn correctly, reduce the skeletal warriors minion count to 0 and then back to what you originally played with or switch the map. the last 2 are only a soft fix since if they die the problem reoccurs.
