Can not turn in the qust for mastodon tusk

Killed the boss in the bone pits the tusk dropped went back to the caravan had a trade request before i turned in the quest when the person i was trading ported to town i had to switch to that persons instance i noticed i didnt have any quest on the right side of my screen so thought maybe i hit a button to take them off screen went into options to find an option for that i didnt see one so i continued on to keth to see if it would pop up i killed the snake boss that drops skill points she didnt drop any and then i noticed i still had the tusk so went back to town to turn it in to see if that was the issue and now i cant turn the tusk in or continue the campaign

I would delete this if i could im an idiot and didnt realize when i ported to the other player to trade it put me in act 2 not act 5
