I don't know where else to put this, but I was on a server making a wall, and I made a macro to make the tip. (screen below)
I was about halfway when I froze for a second. My ghost brick then had the texture of a slope, and stayed that way until trying to step on it. It then turned invisible. The 2x2 piece had turning 2d flat, and above it there was an invisible 2x2 slope. I did not know this until I had tryed to wand it. I crashed.
Has this been done before? Or does Badspot already know about this?
