What happened?

If you don't have all of X resource and place it using the Gui button and come back with more resources it ignores what is already there and places the new resources on top of the old deleting them.
Example used GUI button to place down 8 machine casings. Crafted 22 more. Placed them down using the GUI button. Noticed the numbers didn't look right broke them and there was only 22. It overwrote what was there.
If it was just stairs and polished black stone I wouldn't care but some of these are a pain to make.
