One of the strange bugs I encountered when working with the drag and drop function was the buff not removing when its dragged to the trash can. The weirdest thing about it was it would only happen if you had one buff currently equipped. So after about an hour of debugging I found what I originally thought was the bug which was I left in a debug print string node that I thought was causing the flow to stop and not updating the ui.

But when I removed that debug log I still found the bug persisted. Finally I just tried a shot in the dark and tried doing something that I did earlier working on a different part of the project. And that was simply adding the completed execution pin to the rest of the nodes. After that simple change everything was working just fine.
