I just opened Pre-Alpha and the crosshair isn't centered on the screen, I didn't find any place on the internet with a solution to this bug, so, are runs where the crosshair isn't in the center of the screen allowed?

they are allowed as that is a common issue when playing pre-alpha. make sure to record the whole game screen.

also, if you need help you could use hudsight (it's allowed) and it's free, it has an annoying watermark but it's worth
