So, a few months ago I got all 3 exotic swords on my 3 characters. I occasionally switched them between my chars with the companion app, but everything worked fine so far. Then I stopped playing for about 4 months and now the "Dark Drinker" seems to be missing; I checked all vaults and inventorys on all 3 chars and couldn't find it, it wasn't even listed in the armory (!!!). I am 100% sure that I completed the questline and got it. Also, i can't restart the questline to get it a second time, as it has already been finished. It was a hard grind to get that sword and thus I'am extremelly annoyed by it simply disappearing. Is there any way to fix the problem or has anyone had the same issues?
