Thank you for the suggestion. However, this did not fix my game, it actually made it worse - the x button no longer even shows up on screen, though otherwise I'm still trapped in exactly the same way. As for a VRT or exiting to main menu - I simply can't. When I get trapped in this way, the options menu can't be opened, even though pressing the button to open the menu registers as being pressed (lights up and makes the noise) nothing happens. When my game is bugged out like this the only thing I can do is close the app.
As for quest mode, I'm not sure how the shirosama solution applies to quest mode, because I can't start a new quest. Pressing quest mode from the main menu just jumps right into the quest I'm in, which is bugged and frozen the same way, and all I can do is exit.
Thanks again for the suggestion, but it doesn't seem to have done anything,
