Hi,
Thanks for the excellent tutorials.

I followed the tutorial in a blank project and then downloaded it from GitHub to validate. I am not able to drop a pistol next to a rifle if I move the rifle down with two blank spots on the left. The telegraph will not show for the slots to the left of the rifle. I can also make this happen on the right side of a rifle as well when moving items around. This issue appears in both the GitHub and my separate project.

Thanks for checking this out and updating the tutorial if you find something.

Scott
