I literally misclicked "need" on a blue chest drop from last boss in Steamvault. I saw a mage portal and thought everyone was gone, and I just wanted the loot box to go away so I just mindlessly clicked something. Unfortunately, I hit need and apparently one person was still left (didn't see him) and I won the need roll. He's treatening me with a ban now. I don't care about the item and didn't mean to ninja him.
