The bug that prevents Stella from being viewed in the gallery unless it's directly after a fight still remains in v0.20, same properties and details as what I mentioned under the last version's post. I also forgot to mention in the prior comment that the bug extends to all parts of the shop, not just to Stella's lewd loop.
There's also some smaller issues in Stella's gallery where outfits become stuck and unable to change (as well as one or two other visual bugs), but I haven't been able to replicate these.
