I have had this issue repeatedly, primarily around the turning in, accepting, or required dialogue around quests. Occasionally, when I click on any of those actions, my mouse disappears, although I can still hover and click with my invisible mouse. Additionally, I can’t move. I can mouse turn my character, and that’s it.
Previously I resolved this by logging out, restarting the game, and/or abandoning the quest and trying it again. It has worked every time until now. I am stuck and cannot turn a campaign quest in.
Can someone please advise?
