Intangible Destructibles?

This is not a save file thing, nor anything related to the games directories or anything. It’s been happening for no reason I even uninstalled and re-installed a fresh copy and it didn’t solve it.

The units and destructibles in one of my map are just suddenly unphased by any type of movement. A unit can walk over them and move just fine without even worrying of the destructibles existance or even it’s pathing. The unit just walks right on through it, same with other units. This isn’t happening in any other map; only when I create a map with the maximum size possible from the editor.
