A somewhat odd "glitch" I found in my most recent playthrough of XD.
Right after defeating Lovrina at the Cipher Lab, I rushed and went ahead and fought Miror B. at the Cave Spot. I had forgotten to heal, so I only managed to knock out one of his Lombre before dying. Unlike most bosses, he just ran off afterwards saying "Haha I win!" Problem is, Voltorb didn't appear in battle. Since then, I encountered him once (I critted the shadow Pineco in Phenac), and I battled him in Pyrite Colosseum. He had the Pineco, but no sign of shadow Voltorb (annoyingly, he had a normal one). I also encountered him at Outskirt Stand like normal, and again to snag the Nosepass. But still no Voltorb. I hoped that picking up the list after beating Gorigan would solve this. Voltorb shows up on the list, but the Miror Radar refuses to find him. I'm all the way before fighting Ardos on Citadark now, and if I can't find Voltorb, I won't be able to get Dragonite either, thus I can't complete the game (which would really bug me). Any idea how to resolve this?
