I’ve seen and reported this one before, it’s because the one actual Festron pop murdered another of the pops and replaced it with Festron, just that the portrait didn’t change. Repeat until all pops are transformed.

it also happens with synthetic pops and silicon based pops, which I’m pretty sure is not supposed to happen. I guess technically Baratak would be immune because the Festron seem to be pure carnivores, but the difference isn’t as much compared to silicon based and synthetic.
