I've been working on league medals, and have followed all the guidelines(texture size, format, polycount) and can preview the medals via the workshop submission tool, but when I try to verify the item, it gives me the error below.

As I mentioned, the polycount is 938 tris, which is approx 18 tris less than the medal that was created previously, which is in-game. Any help would be appreciated.
