Was going to try and 100% complete this zone and it showed a quest at the dig site even though I was sure there was no mission there and the mission is the same name as the one offered on Sanctuary. I went to the location anyway and there is nothing there as expected.
I assume this is a bug and it’s placing the quest marker there because Tannis was there earlier? I don’t know but it’s weird. After completing the mission on Sanctuary it’s also gone from The Draughts. I’m still only 97% complete though for some reason…
edit: GG Gearbox. I can’t put the actual name of the mission in the thread title because it’s a “naughty” word apparently…even though it’s your own damn quest title! Censoring your own sexual innuendo. Now I’ve seen it all.
