Not sure if this is a bug but I just noticed that when inserting part 87620 and 2462(2x2 and 3x3 angled bricks), the parts are inserted at it's top snap point. Most(if not every) other bricks are inserted at it's bottom snap point. So when selecting the top snap point of an existing brick and then inserting 87620 and 2462, they will be placed at the same height as the existing brick and not on top of it. Not a big deal but a little annoying... 😃
