Hi Rob,
Please can you send some screenshots of the regions which are wrong, and draw on what they should look like. Sorry for the hassle it’s just a bit easier to see it visually, and then hopefully I should be able to see what went wrong. Probably the reason has something to do with the way the script moves the boxes around, as this is done by for example to move the box in the x direction it will be scaled to twice the size in the x direction from it’s origin point then shrunk to have the size by it’s center, when this is done twice the box shifts along by exaclty it’s own length but i guess in your case the scaling has gone wrong for some reason.
