So I got this Zaouli's Bane from one of the Pantheon truimphs back when they were bugged. This gun, luckily, wasn't super busted with fully blank perk columns. Only thing I was missing was my second perk in the 3rd column. Problem now is even though I've upgraded the weapon to Tier 3 Enhancement, explosive payload (the one perk I have in the 3rd column) won't get enhanced. See the posted image. I hope this issue gets fixed so I can actually fully upgrade this raid adept. Has anyone else encountered this bug, and if so do you have a solution? Thanks
