As the title says I've run into an issue where my Rest button seems to be permanently greyed out. Tried restarting the game and rebooting but no joy. Can still sleep in inns but not being able to rest is becoming a serious issue. Is also preventing me from progressing a Soulbound item. Any ideas?

I have the exact same issue but don't have 2 screens so all I can see is the top left corner.
