It continues to happen on any console platform ever since the game was first released. I cannot believe this has never been looked into and resolved!
Switching between set 1-2, casting CTA shouts on switch and teleporting creates the problem. Not sure what button combination or when it glitches exactly, but does not seem to occur without using them.
Personally spent over 3,000 hours with this version of the game so far and can absolutely say that my preferred mode of Legacy in Resurrected is broken. We are basically forced to use Modern, unless you enjoy playing with half of the sound or literally restarting the game every 5 minutes.
My first post and thread was made about the same and ended up being ignored completely.
