Showed this to a Unity dev whose theory is that the game is using flick prediction which should be mobile only, but is being used on PC. The theory is that the game is predicting which box you want by which ever way you “flicked”. Flicking only makes sense on touch devices though.
I tested that out on PC myself and sure enough, I can duplicate this bug every time. Going to add my own video for the devs then. To do this every time, keep your cursor in the same box but flick towards another without ever touching that box.
@beeflog, this happened to you because you flicked the cursor up, even though you didn’t touch that box.
Hopefully turning off flick prediction is easy, but who knows.
