When pressing T, you lose control of all inputs. Even menu can't be opened. You can see your curser and have to Alt+F4 the game and restart to fix it.
Hello,
We have a fix currently in Live, we'll be merging this post to the one marked for Live to increase visibility.
Thank you!
you can actually get out of this and is mentioned in bug https://playnightingale.ideas.aha.io/ideas/BUG-I-604.
this one is realy sad .. I don't know if it's T or another key but I had it a few times now .. focus of the borderless window is lost, and you can't take it back. everything works (mouse, etc) in windoze, but you can't go back to the game which is still ongoing .. result > ALT F4 and relaunch. . . and you spawn back in the vault you where in.
