I’ve just started up the game and when I clicked on my secondary monitor to minimize Steam while the Crate Entertainement logo was displaying, the game switched to my secondary monitor instead of the primary one
Not a huge deal but I thought I should report anyway
there is a hot fix which worked for me: set the game into window mode → drag the game to the screen u want and set to full screen mode once again. Even after restarting the game it should appear on ur selected screen / monitor 1.
