No, but this happened after I deleted some residential buildings to make space for a subterranean housing module
But it's not because all of those homeless people are from the residential complexes.
People just left their homes after I replaced the 6 residential complexes that I deleted.
And it's getting worse, because new colonists don't want to join in even though I have a lot of landing pads and 3 cloning facilities.
Update: people are slowly going back to their homes and new colonists are joining in (I just didn't see any diference in the colonist population number)
