What's wrong with my Dynasty Warriors 7? Part 2

 I tried to play again after a good night sleep, and... oh man. I picked a random mission, and selected my tuned up Cao Pi. As soon as the mission started, my allies started HITTING ME. I tried hitting back, but my moves would go through them. I figured the game glitched, so I paused the game, to pick "End Mission" but as I went to pick the options I noticed... the game wasn't paused at all and I was getting hit!. Worst part? After I picked End Mission, the game just... unpaused. I tried again and same deal. I figured I'd just kill the enemies and be done with the mission, right? Wrong. Both enemies and allies were had it in for me, and  I was managing pretty well, untill I noticed... whenever I killed one of the enemies, my Kill counter wouldn't go up, and their HP would refill.
 It gets weirder. I started running from them, and Cao Cao appeared on top of a Black Red Mare. Weirder yet? It was Cao Cao's face on Lu Bu's body. He signaled at me, the PLAYER, with his sword and emitted a sound... the same sound from the glitched room from yesterday. Then a "Failed" popped up and I was allowed to exit the mission...
 Guys, I don't believe in supernatural stuff, but I'm pretty weirded out right now. I'm getting goosebumps just thinking about this. Should I keep playing or throw away my disc?

UPDATE: Koei's response:
Dear Ignacio,
 Thank you for purchasing DYNASTY WARRIORS 7, we recieved your inquiry, and this is the first time any of us at the offices had heard of anything like it. I asked the translation team and they said that no such line was recorded or even put into the script. My co-workers at QA said that your console might've overheated, and you probably thought that you had heard it. If problems persist, send us your disc, and we will send you a new one.

 Right, 'cause sending them my defective disc is totally posible from where I live. Regardless, I'm sure, SURE that I heard what I heard. Since my friends kept egging me on, and just to prove Koei wrong, I will play again tonight, when one of my friends comes over to check this out.
