What version does the game say you are on when you open the HTML?
Because in my fresh-ish save (8.4.1 A18a) I have Talika, Zenobia and Akari Ito and they have 0 issues with wardrobe, while some you mentioned like Rosita don't have wardrobe yet.
If you're on an alpha version, bugs exist and if you wish to avoid them, wait for a stable version.
The alpha version doesnt show any version number in the http . But I tried it with both. Same issue. No, I didnt start a new game to check if the issue is save game related. It would take some time to get to the point where I would have access to these characters.
Maybe Rosita and the rest had full set of clothing since a few updates but no one reported that they are missing because noone realised it?
Rosita has a full wardrobe in her folder, same as every other model I mentioned. They just dont seem to work ingame for some reason. I dont know for how long the models had a full set of wardrobe, this is the first time I realised that the clothing I put them was replaced by a place holder. They are replaced by a place holder, it is not that I see a blank page as if it wasnt loading properly.
I got an idea... I am going to try to delete the place holder images from their folders to see if they are not the cause of the problem here. If I dont edit this post, means that I took the place holders out and it did not solve the issue.
Edit: No dice. The stable version does not include the new wardrobes of some of the models like AV203 (Akira Ito) to begin with. But the models like AV126 (the red head with the scars and a roman bronze roman chest plate) that had a fully functional wardrobe in the last major update only shows a place holder on both the stable and the A18b alpha version. Which is highly weird because they dont even have place holders in their folders!^^ So where are those place holder images come from?
