the only issue with zonebricks is the fact you cant place water bricks or other zone bricks inside (since theyre pretty much labeled as water) to overcome this however, I had the idea of simply disabling the zone bricks altogether to create floating bricks, but that would be troublesome since I would have to restart the server back and forth and they could be deleted by simply ctrl ZING
Marbleman created an override to the brick system however which allows for brick to be placed into the air and inside eachother without worry for support, so that may ease things up a bit
