I will try to explain what happened. Basically I was playing as Sora and I had entered bonus time while fleeing from some enemies. I noticed a chest(the last one before Sora's final battle I believe) and ran to open it. I ended up opening it from the left of it after Sora should have dropped; the opening animation played after bonus time ended. Then I played as Riku as normal and once I regained control of Sora I was just falling, as seen in the video. Fortunately I was able to glide my way to safety. If I didn't have glide equipped I fear I would have been stuck in a loop forever.
