Trespasser DLC can't progress
Currently I'm stuck in the Winter palace area. I cannot progress because any interaction with an item, doorway or the eluvian causes the game to no longer load the next screen, remain frozen on the item message or cannot click anywhere.
I will refer you to an old thread on this that some people found a fix for their issue, and with suggestions made by myself and others as things to try.
Modded Characters other than your main also cause this issue....so trying a different party mix may help too.
