Unfortunate that gofile has a tendency to delete files quickly. If the plugin is small in size (I have no idea) it would be better to upload it as an attachment instead.
Could you share Haanja's portaits? Does she have any ero tachie? From the asset table you posted, I believe the relevant info should be:
"m_VirtualPath": "Design/Character/NPC/Haanja/Portrait_Haanja.prefab",
"m_AssetBundleName": "698bd8b252436452c2e6e510829f7",
"m_Guid": "1bfc546b05e9702479063efa155f4003"
I can give feedback to this. If you look at the transparent dress, the portion over the belly has different shading due to parts of the dress folding / the way the light hits it (shading). However, this was carried over to the belly where there normally isn't "folding dress material". As such the shading from the transparent dress, meant to indicate draping material, makes the belly look kind of like draping material, i.e. fat. She looks like she's carrying 10 extra pounds there.
Basically the fix for the weird belly would be smoothing the skin tone / removing that bit of shadow, similar to what orhee and imlyrin did roughly 40 pages back (though dirty version).
