Asymmetrical block shapes should come in left and right versions

I'm testing the new Building Update, and it's a lot of fun. I think we'll need a left and right version for any block that can't be made into mirror image of itself. I'm still exploring which blocks can't be flipped as mirror images-- it takes a while to figure out if a block really can't be flipped.

you are correct! Thank you I should delete this post if I figure out how
