itch.io

So unfortunately the way that Itchio works, the only way I can "update" a file is by uploading it under the same name. My biggest recommendation would be to check the Version that your PDF lists (on the front cover of the mechanics shop and the credits page of the core rules). You should be able to cross reference it with the full downloads of both of those in the "demo" section to get the most up to date version ((or you can always redownload the full Zip which will always be fully up to date! ... minus the Cross Overs which I save to fully add in until I finish updates to the main stuff))

That said I'll deffo add a note into the Zip of which version the folder is!
