Wow. Just wow. It only glitches for me, doesn't it? It only seems to really happen to me.
Example : I was just building a brick, but when I pressed the undo buttons (, before cancelling the brick ), it just deleted a random brick in a random colour in the place of that brick that never existed, and when I was building red bricks, they came out white. Wow. Just completely wow.
EDIT : I will post proof in pics when I next find the glitch (/es).
Yet another EDIT : Sorry if this goes in Drama, or Help, although I wouldn't've thought it'd go in Help because I'm not asking for help, I'm just saying how idiotic my laptop can be.
