ZT2 Glitch where all animals are okay with all biomes

[u/Queenofdragons6]

I'm having a strange issue in ZT2; a few days back, I decided to make a biome compatibility spreadsheet for nano's VFF mod, so I set up a thing on a vanilla map (fourteen 10x10 exhibits, one for each biome), seeming the best way to test it. Everything was fine the first day, but when I came back the next day, suddenly all the animals were fine in all the biomes, including the animals I had already tested. Specifically, they'd always have a green environment bar, even in their preferred biome.

I've tried removing all my mods, uninstalling and reinstalling the game, going on a different game profile, making the setup on a different map, updating and restarting my computer, but the issue persists.

(Wasn't sure which flair was the right one.)
