If anyone hasn't been to Sanctuary yet, I'm dying to finally complete my glitched "DO NO HARM" side quest. So let me know and we can add each other (we could also get the "revive someone on your friend's list challenge). I'm on X360. Hopefully Gearbox has a patch soon or else I'm going to either have to wait until Playthru 2.0 or luck out and find someone around my level (15) who hasn't been to Sanctuary yet (zero chance).
A lot of people aren't able to finish the quest. You go to Zed, it does his cutscene, then he tells you to go to Tannis and her cutscene is supposed to happen, but if it doesn't, then you can't finish it. It'll just say you spoke to Tannis but you can't turn it in. When you do talk to her, she just keeps doing the save Roland dialog.
But if you can do it in multiplayer with someone who hasn't done any of that, then you can go back to your game and skip it and bam, sidequest done.
Edit: Typically you can't go see Tannis at all until you see Zed because Tannis's cutscene will trigger if you walk into Roland's hideout.
