I keep on reloading to my last save and I only get the dialogue of Tolfdir missing his alembic's and the quest does not start or appear so the alembeic's do not appear can anyone tell me how I can sort this?
If you look at the quest page the quest won't be added to the journal, check the three possible locations (they are listed on the page) and see if the alembic is there. If it isn't and your on the PC try spawning it with the command -
player.additem 00026C31 1
If your on a console and reloading a few times doesn't work reload again and don't get the quest theres nothing you can do really (the reward is only tiny bit of gold and a random soul gem so your not missing much).
