If I remember correctly, there have been spots that are supposed to be non-buildable that were buildable at times, only later for the bug to be found and then it goes non-buildable. The base won’t 'splode; it just suddenly can’t be expanded. So if someone is built there and they go to place a bedroll, a new chest, whatever, they will get the “Cannot build here” and that would be a queue to gtfo of Dodge.
