So I am currently doing the "Messages Across Tamriel" questline.
My current objective is "Enter Vanus Galerion's Portal"
The portal was created but I didn't enter because I wanted to go to my friend first and complete this later.
When I returned to the Mages Guild in Daggerfall I saw the icon on the floor but there was no portal (better explained in the screenshot provided).
I have no way of continuing the main quest because there is no portal.
I've tried restarting (for longer than 15 min), re-entering the guild, cant abandon the quest (mainquest) etc.
I have tried to contact the Bethesda/ ESO Support with tickets, on twitter, in game etc.
Their customer support is absolultely trash; I get the same stupid messages telling me to ask the forum. They take no time to read my message
I don't know what do, please help, thank you.
