Anyone else having the problem that your explosives randomly stop working. I use any explosives on one enemy and nothing, one next to it, dead.
I use VATS on the immune one and the health bar shows nothing but with Living Anatomy I see it has full health. I use a grenade machinegun and it does take damage from the impact of the shell itself but none from the area effect of the explosive.
This doesn't happen when starting a new game but after I level up a bit it starts to happen. Not sure if it's a perk or what, any help would be great.
