I'm unable to get credit for Large Storage Fragment and Rust Covered Disc, I've had them in my bags and completed the quest several times. This quest as far as I know doesn't get flagged as completed because it's repeatable, but having the item in the inventory doesn't provide credit even if refreshing ATT.

i just marked the quest as a daily. if you don't have "show incomplete things" checked on the first tab of the options, it shouldn't show up now. if your issue isn't fixed once you pull the latest git commit (or install the next release, if you use twitch), reopen your ticket, please!
