I just started to encounter a "glitch" where the Super Mutants, once killed, freeze in position and can not be selected for ammo, caps, etc rewards. I, the player that is, can walk right through each mutant. I'm at level 37 (approx.). There is no CTD or problem with the game, my companion and I can continue as normal. Puzzling predicament as the last encounter required a key from the "boss", but couldn't get it.
Any help would be appreciated.
