I did not believe it at first but it appears when I remove 8 bundles from any spot on a junk pile that it kills that spot, forever. It won't even produce an items when scavenging. Is this true?

If I remove 7 bundles, can someone come behind me and remove the 8th bundle killing that spot by accident?

If I remove 1-7 bundles, will those bundles eventually regenerate? If so, how long does it take?
