The avatar bundles with required modesty layers are applying 2d clothing textures to the body parts.
This isn’t seen in the preview on the item page, but once purchased it applies to the character and causes issues with the UVs.
There are workarounds for this problem (which I’m doing in future bundles), but it seems like an issue that will be an ongoing problem as more people upload bundles (as it doesn’t show in most phases of testing). Perhaps a way to retroactively disable 2d clothing for bundles in the configure screen?
