So after I downloaded patch 2.0 everything was fine until I started playing with some of my old guns that already had the extended mag perk prior to the patch. Basically the perk doesn't even register anymore even though in the patch notes, it just said the extended mag perk was to be reduced by 33%. I tried switching it back a few times and the perk had no effect. This "glitch" ruined some of my favorite guns. Anyone else having this issue?
