Lost enchanted weapons! (Doom (2016))

Hello!Actually the question in the topic title!When pumped the gun for the glasses-put on the shotgun the ability to fire a grenade-after a while it stopped doing it,to the assault.rifle mounted missiles-the same missiles are no longer bullet-maybe I'm just a noob and missing something ,or maybe it's due to the fact that the pirates game with me?Thank you all in advance!
