VJ Npcs will break

[TRY0NIGHT]

So me and my lads use npcs a crap ton whenever we do fighting stuff, and I know that ACF was designed for player PvP but we saw a rather large problem whenever we tried to use any ACF Missiles variety of weapons against any VJ npc. Any other normal acf cannon or gun that came with the base seemed to work fine with npcs and VJ npcs but we noticed that whenever we used a missile or bomb from this addon, it would rarely actually kill a VJ npc and 9 out of the 10 times just break the npc, and when i say break them i mean It will just make the VJ npcs invincible as if they did not have a health system. I don't really know what may be happening here so I decided to come here to see if anyone could help out.
