You are able to press E to use an arcade machine at the same time you click on an icon on the map to fast travel.
Steps to Reproduce
Walk up to any arcade machine.
Hold TAB to open your scoreboard.
Go to the MAP tab on the scoreboard.
Click on any location at the same time you press E.
What I expected to happen
Either I do not fast travel and play the arcade machine, or I do not play the arcade machine and I fast travel.
You fast travel AND play the arcade machine, putting yourself in a glitched state where your inputs no longer control the game (but it’s still “in use”). This also keeps the HUD for the arcade game you tried to play on-screen until you disconnect.
