Then you’re doing it wrongof course, of course @KiiWii but see also the fact that the most common is to obtian base game and update from different sources, and even that, sometimes both are married... etc etc.
We need a tool that say that to us without to have to install on the console, is the way.
I obtained gun club and the update yesterday, same place, married and working fine.
Presumably if you download FPKG updates long after the original game FPKG (and/or it’s from another source) it stands to reason they aren’t gonna match.
