For a month or so, I’ve had a repeated issue where the game hangs while trying to enter an echo, and then timeline stability is reduced (counting the hang as a death) when I need to crash/restart the game.
When this happens, the game hangs 100% of the time when I try to reenter the echo. The best I can do in this case is to run other echoes (hoping they don’t also hang), since this sometimes makes the original problem go away.
This seems to happen most often with quest echoes, but I currently have a character stuck in the monolith due to these hangs. I may just abandon the character for now.
But I’m also reluctant to create new characters, since this issue could stop their progress as well.
