A game freezing glitch!

Alright so we know most gliched objects that we import from lbp1 look and work the same in lbp2 as they do in lbp1. I was messing around in lbp2 with glitched materials that I made in lbp1 and something made my ps3 freeze.
When it happened, I was in create mode using my popit trying to copy and drag a piece of glitched dark matter from my lbp1 profile. Its the glitch that makes material smooth and shiny when you expand it, cut out a small piece, then expand it again and keep doing it until it looks shiny. The glitch in lbp1 makes any material appear smooth and shiny. I had no problems with it in lbp1. In lbp2 it looks the same as it does in lbp1 but in lbp2 it made my ps3 freeze.
So if any of you know about the glitched material Im talking about, BE CAREFUL WITH IT IN LBP2! Before you use this glitched material in create mode, save your level or backup your profile to avoid loss of progress.

Yeah, that stuff is extremely unstable. Seems those materials' glitched state brings out the tiny rounding errors in the physics calculations and amplifies them. And if you amplify that effect enough, the game tries to divide by zero or something and crashes. But you say they're even more unstable in LBP2...

Yep. In lbp1, when the material starts shaking violently, it breaks and disappears?!?!? end of story. But in lbp2, I played around with this glitched material only once and everything froze. If anyone wants to experiment with this glitch, be smart about it. Save your progress first.

I used it in Beta, and even have 1 that flys around the room, they still work fine for me. *mew

I don't think anything's changed here between LBP and LBP2. In LBP, I've had these things freeze the game occasionally just from putting in a bunch of them from My Objects. And it's very easy to intentionally do this with them: once you amplify the effect enough, simply cutting them in half will cause a game freeze.
