I downloaded the starter cube and when I view it from the right or left the 'divisions' of the squares on the faces are irregular, when the top, front, back and bottom look fine.. me thinks gremlins have already begun to transform your starter cube. Muahahaha
But seriously, some of the divisions lean left some right / and some are the opposite of the far side and show as an 'X' in the other views they are 'X's why aren't the left and right side the same?
nuf said, Cheers!
Edit,.. Pics help..
Front, back, top, botom views look like this..
Left and right look like this..
See what I mean?
