(Okay so not sure which category this belongs to, but I figured this works best.)
I’m beyond happy the “Infinite Homeless” bug got fixed so fast, kudos to the devs! 
The “congregation” of the clone NPCs seems to have been solved by today’s hotfix, but I got a lingering “problem”… which is that a lot (maybe even all?) of the clones still exist in the town, or at least they seem to make up to 70% of the NPCs appearing in my business.
This isn’t game breaking, just immersion breaking, so I’m mostly looking for solutions people might have to “refresh” the town population, to force some… diversity 
My only idea is to set the aging to something crazy like 4x and just hope old age kills them off lol, but it would be drastic.
