I'm hoping there's someone who can assist with this These two files have broken LOD1 and morphs, so they don't appear at all in CAS.
If someone could send me working files, that'd be appreciated! Or even the base LOD1 (with morphs is appreciated but not mandatory), so I can fix them.

Sporty Skirt - fixed with help from @peter9g
Vintage Baseball Uniform

Hi SweetDevil

For the Sporty Skirt the LOD1 is in DeltaBuild0, as listed in the _XML resource from afBodySportsBaseballVintage.package, so this outfit shows up in CAS in my game (version 1.67).
I don't have the Vintage Baseball Uniform though.

Hope this helps

Hopefully this package file has the lods you need:

Thank you very much for the assistance, Peter! For some reason, the Sporty Skirt uniform showed up in my game after I added the LOD1 GEOM from Deltabuild0 to the package

If that is the package from that source, then I'm afraid it's the same version I have, without the LOD1 base and morphs. Poking through it, it does indeed lack them.
However, I'll look into the XML, as peter9g suggested, and hopefully that uniform used a basegame mesh too

Edit: after poking around, it seems to be the same thing! I updated the posts in the OP with the fixed versions of the Store items, in case anyone is experiencing the same issues as me Thank you for the help! I learned a few more things today thanks to this.
