I had posted in Rules Revisions regarding free roam months ago and nothing was done. I'll do a revert as soon as something is done, since there's not technically anything against it currently.
As for the rule you pointed out, that would also cause issues with Sand Ocean and Cannon's Core (namely Sonic's part) in SA2(B) and Sonic's Ice Cap in SA(DX) since they have timestop methods that stops the timer and let you complete the level with the timer still stopped. Wouldn't that mean any rings you get after stopping time on those levels not count? Similar thing goes for score.
Exactly what is that rule referring to? Is it trying to say not to submit anything you get before completing the level?
