That is a steam cloud issue , i get the same when tried to upload my skinpack from my accound for some reason the item is in cloud but not updated and it catching cloud space , that was the reson that used 2nd account to upload, there are many problems and valve have not respont yet in my tickets, I don't think that is…
puppet I don't think that must be the point , it's not relic's issue it is cloud space limitations , I think that is the only way for Grumpntug to upload the skins with all details and his work.
F_X nrm files though may change the amound of skinpack . i.e a german skinpack summer version is close to 180 MB with the cloud upload limitation of 200MB so if you add nrm the skinpack wont be individual.
