It is Autobridge. Autobridge doesn't make a brick underneath you if your standing on a surface.
Bricks count as surfaces right? If it were autobridge, how could it be planted inside the top brick?
I knew it was the work of autobridge the second I saw the first picture.
To be honest, I really don't know how that one happened.
I think it was texture lossNvm, if it were, i couldnt stand on it. That happened a while ago, like july 2008.
Kk, im going to bed, ill post YET ANOTHER proof video in teh morning. I Iz tired..]
Good night people!
