So as the title suggests I'm kinda completely stuck now. The quest objective is stuck on 'Complete the trials of the Tebaru Sanakis with Yatzli' 'Proceed to the second trial'. I've gone through the whole area all the way to the end and making the choice at the end of the quest as depicted in the screenshot. But when I speak to the archmage for them to do their thing it cuts to them, I see (sharp breath) and then it cuts back to me. And because the game auto saves every 5 minutes the last save I have before this bug was a manual save from yesterday, which by now is about 5 hours of gameplay. So is my save just completely bricked? Because my enthusiasm for the game is dead atm and I don't have the energy to redo everything up to and including this quest when I could potentially get the bug again.
