Green Grove Act 2 has an interesting bug in which during the time challenge, when you get towards the final ring, there should be a Scouter badnik nearby. Doing the following triggers an interesting bug/glitch.
-Lure the Scouter near the goal ring, in which it follows Sonic's position and movement
-Jump and activate the final goal ring
-After the animation finishes and Sonic hops down, have him aligned so that he destroys the badnik and moves back towards where the goal ring is.
If done right, this happens.
This doesn't affect the game, but Sonic retains his ball animation when and before the light beam appears before being transported away into his second "twirling around"animation. The beam is also dependent on where Sonic is, and as this glitch keeps Sonic in the air, the beam will not hit the ring, and will uncannily hover right above it.
I hope to gather more bugs and glitches as I accumulate more playtime on this beta patch.
Will fix
