Bugs my group found whilst testing this addon(Sorted from most gamebreaking to least):

1) Virtual Zeus can be hit and even killed via melee
2) Players/AI that had "disabled damage" could be damaged and killed via melee system
3) Anything bound to key "F" will bug primary weapon in a way that you cannot reequip it afterwards.
4) AI in combat mode cannot be silent killed even though it did not spot the player
5) Player cannot silent kill other player
6) Well timed kicks can kick unit through the doors and walls(Walls are harder to get kicked through tho)
7) Players that are held captive via ACE can still use melee system. Videoproof here: https://www.youtube.com/watch?v=jn-zwEyjJ1g
