Eggman probably used the space-time warping powers of the Phantom Ruby to capture it again.Is it chained to Angel Island now or is Angel Island parked right next to Mirage Island? In the backstory of Sonic CD, this mystical planetoid only appears over a lake in the Mirage Island that Sonic 4 would later take place in, but in Mania, it is very close to Lava Reef in Angel Island instead. Little Planet is suddenly chained and turned to metal again for no given reason, even in the manual.Regarding the "Super Emeralds" in Mania, Word of God is that they're actually stone replicas of the real deal.Perhaps it warped the island so quickly that Knuckles didn't even notice it happen. Its ability to warp time and space may have affected the Master Emerald/Super Emeralds and caused Angel Island to go down to surface level.

The presence of the inactive Super Emeralds also only raises more questions. In Sonic 3, it was brought down by the Death Egg's crash, but nothing of the sort seems to have happened here and Knuckles is unconcerned in the beginning.

The Master Emerald is resting at its shrine as it should, yet Angel Island is on sea level.
