glitch/bug with grenade launcher shotgun weapon mod

[Chuu]

when i shoot the grenade launcher with shotgun it does not ever explode anymore.
the gun is glitched and i cannot use it for its intended purposes any longer.

looking for a solution to this problem.

Unequip and re-equip mods and, most importantly, don't use all runes cheat again - that's the cause of this bug.

I bet its for the imp challenge correct? This exact thing happened to me a couple of minutes ago. All you have to do is load a level with only the IDKFA cheat (thats whats causing it), then bring out your shotgun with the grenade launcher equiped and hold ONLY left click to fire, then while still holding left click, change the weapon mod to full auto, then back to the grenade launcher. This is what worked for me, but if it doesn't for you I think there are other ways to fix it.

Oh the IDKFA cheat is what caused it to break for me

i didn't use any cheats. but replaying past missions to try and figure out what was going on randomly fixed this issue.

so this is resolved.
