I've discovered a strange bug with models imported from LDD.
If you import a model and then add a piece to the model in mecabricks in the same color, the color selection tool doesn't work properly. It will only select LDD imported bricks if you click one of the imported ones, and will only select the one added in Mecabricks if that one is clicked. They show the same color in all of the info bars. The bug not a big deal, as its easy to work around, but it can be annoying.
