If this hasn’t remotely been your experience, how do you know rainbow flicking fixes it?
The game is widely known to have multiple bugs affecting gameplay, from lags and desync issues, to crashes and even teams changing colour mid-match. In this case, and this is the second time I’ve seen it, the ball glitched into the ground after randomly bouncing around the pitch following a shot against the post befote finally getting stuck. It couldn’t be interacted with at all.
Great game, but not exactly polished yet. This isn’t a wild take.
Can’t avoid bugs that randomly occur through normal gameplay unfortunately.
You’re very lucky not to have encountered any. There’s countless videos and reports of them online, and Sloclap have promised to address them.
