Don't know if anyone reported this or if this bug is just on my side, but if you are in your bedroom, open quests, then open completed quests sometimes you can still click on the bed which causes some object in the bedroom to appear and you can navigate around the world but the completed quests menu is still open. You have to fight the menu for a while to get it to go away. I also found out you can always click on the bed in the completed quests menu it just around where the Main character sits in his chair. Around the metal part of the arm of his chair and the seat.
After I typed that out I found out when you are in the bug just open quests, story quests, and then click the X in the top Right. Or when the options for the bed pop up just click on the X in the Completed quest menu before interacting with the options for the bed. Another thing is if you have the options for the bed open then open the completed quests menu, the spot for where you can click on the bed changes to the middle.
Its also safe to assume this bug happens with anything you can interact with. Just watch were you click when that menu is open.
Edit: I decided to try it out and don't open the menu when you are outside where you can travel. I made the mistake of opening the menu outside and traveled to the chamber (I was clicking around to see if I could travel. Not specifically going to the chamber) and now the X in the completed quests menu does not work anymore.
Edit again: If you happen to do what I did and travel somewhere with the completed quest menu open just travel around to different places and follow the steps of escaping the menu. Sometimes the X works.
