When I quickly move an item from one column to another empty column, the item gets deleted from the list.

If the column is not empty, there are no errors.

I had the same kind of issues and the reason is that you are missing a case scenario in your dragOver or dragEnd functions. To find the issue you need to console log over active and over and see what's happening when you do a quick drag. It's tricky to make it right especially when you have 2 levels of drag and drop.

Thank you.
I found another example. I haven't checked it in detail, but it works well.
