I'm kinda bored, so I wanted to talk about glitches and bugs you might've found in any video games you've played recently.
Right now, I've been revisiting Sonic Adventure DX, and weirdly enough, in Knuckle's story, after you've beaten the final story, for whatever reason you'll find another Knuckles alongside Dr. Eggman lying on the ground in the Mystic Ruins near the Master Emerald! This is probably an artefact from a cutscene used in the final story where Chaos has attacked Knuckles and Eggman. Scarily, though, if you move around, the cutscene Knuckles on the ground will jerk his head around in the same direction the playable Knuckles is moving!!
