I noticed that wolves are acting funky when dressing with apparel.
If a wolf is wearing something (CA or regular) and you remove it, the screen does not fully reflect that the piece has been removed.
As you can see here, the monarch cloak was removed and since it's now "below" the layer of the sand collie cover, the other CA clips through.
It's only clothing that was already on the wolf when you go to edit apparel that is disappearing. Naked wolf? No issues, you can dress up as normally with removed apparel being reflected immediately. Wolf has any apparel on? Whatever that apparel is, if you remove it it will not go away, it will simply become the "bottom" layer, visual glitch only. Wolf has apparel on and you're just adding to it? Whatever you add will be unaffected, even layering will properly work.
When you save and exit, all the removed clothing stays removed, and anything added stays added.
So just to clarify:
Wolves with clothing already on will appear as if they're still wearing those clothes when the item is removed. This visual glitch goes away when the wolf is saved and the player leaves the dressing room.
Wolves without clothing already on are unaffected.
New clothing added in the dressing room behaves normally. It is only clothing already on the wolf that doesn't.
ETA: Transparency in all apparel seems to be not working in the dressing room also. This issue is ONLY in the dressing room. The wolf, when wearing apparel with less than 100% opacity, will show the apparel at a much higher opacity than it is until the apparel is removed, after which the apparel will still show on the wolf but be at its intended opacity. The apparel is "removed" from the wolf (as in, not on the apparel list) but still shows up on the wolf at the correct opacity in the dressing room. @/SovereignFives has tested and it seems the apparel is being duplicated! That's why it's showing up as more opaque, and why the wolf is still "wearing" a copy after removal.
The dressing room and duplicated ones are significantly more yellow than the normal one.
