Once when I was playing BG&E (I have it on PC), I encountered some strange glitches and happenings! Here they are:
1) In the Nutripils Factory, where you fight the DomZ robot, I'd started the fight, when suddenly the screen went blue, my health went for no reason and Jade died! Then, when the fight restarted, it was really wierd - when Jade and Double H appeared, all that could be seen of them was two pairs of legs with a long line stretching to the DomZ robot! When I started hitting it, Jade reappeared, and when I got Double H to attack, he reappeared!
2) Another time, I had the same glitch, except when the screen went blue, I kept eating the K-bup boxes to preserve health. Then suddenly, I found myself in the lift you go in after the fight, on the floor outside the room Double H was tortured in! Plus, the main elevator was working again and I was able to go up once again! When I made my way back to the loading dock where you fight the robot, it was still there, trying to attack me!
3) Another time, when I was in the Slaughterhouse, getting the code to open the portcullis thing so I could get away (I'd done the report), Double H vanished!
4) Once, in the volcano treasure area, Double H disappeared. When I looked for him, I find him; he'd somehow fallen down the pit and was stuck at the bottom.
5) Lastly, when on the landing platform in the lunar base (with the big space battle going on all around), I went to the elevator with the three switches that leads to the DomZ High Priest. As usual, Double H and Pey'j got on too, and went on their switches as I went on my. But, at the last second, just before the elevator started moving, I moved Jade off it. The elevator set off, with only Pey'j and Double H.
