SK Epic Quest Faction Question (Duriek Bloodpool for Corrupted Ghoulbane)

[remen]

So my question is for the SK epic hand in to Duriek Bloodpool, do you need better than indifferent faction? For the rest of the quest hand ins so far, indifferent has been sufficient. A few days ago I did a hand in of Ghoulbane, Soul Leech, Blade of Abrogation, and the decrepit sheath to get the corrupted ghoulbane, and he took my items without giving anything back. I could have swore I double checked my faction with him after opening the trade box and he was still conning indifferent.

The GMs already responded to my petition that there will be a reimbursement of the items (TY GMs!), so this time when I get the items back I want to make sure that the hand in is successful. Can anyone confirm that indifferent faction is all that's required for this step, or is better faction needed? I suppose it's possible I moved slightly by mistake right before handing in which broke my hide, but like previously mentioned I thought I double checked faction to be conning indifferent and the hand in was unsuccessful anyways. Also, other than faction issues, is there any other reason this hand in might not have worked? Thanks for any answers!

Edit, info from GMs regarding the failed hand in:
