I love how easy it is to make little dramas in your head about this game!
Exporting didn't cause the bug. I didn't want to meddle with the stats. So I wasn't exporting the data. After Kristy was in the gantry feeder, I saw she got addicted to donuts, so I exported the json to futz with her addiction in there. However that was after she turned into a defacto feedee.
Okay, I tested it with my file were I originally started this run.
And luckily, I didn't import a file inbetween since I transferred it to another system, the Gantry Feeder thing happend and now. So I had a clear testing area.
I did start some new Runs since then, but the original Town stayed the same.
Sadly it happend basically the next day.
So it is either a bug or actually intended to happen between two Feeders after some time.
Since you confirmed you hadn't exported the file before it happend, we can rule this out as the source of the bug (if it is a bug)
