So I've got the no quest indicators or map markers indicators bug, which makes grouping near impossible and basically only farming possible on solo since can't find the quests no markers...and I say, hey, I'm gonna go into Cyrodiil and try my new build and about 15 minutes in I'm feeling good with survivability and sustaining a lot more damage, not dying...and the whole battlefield freezes and now infinite loading screen.
This is making my return to Tamriel after more than a year in Afghanistan (I shipped right after Craglorn started up) very unpleasant, I'm sorry to say. I even splurged for the sub.
There is another bug that might be tied to this one. When you die and release to a keep or Elswyer shrine, sometimes you get the never ending loading screent.
If you close the game out, and restart game, and log in your same toon, you still have the never ending loading screen for Cyrodiil. You need to log in a different toon, then relog your Cyrodiil toon to finally spawn at the keep or shrine again.
