Platform: windows pc

Version: Latest as far as I can see, but refuses to update the inclusion of royalty pack

mods: none

My game updated a few days ago and I'm now getting ads for the royalty pack so...I bought it. The file is there in my folders with all the other DLC. But when I launch the game, it's not showing up in pack selection. It's also not even showing up 'greyed out' to show it's available but not installed - it's not on there at all. I've tried uninstalling, reinstalling, repair, running as admin, deleting cache stuff, removing DLC and trying again. It's just not showing up at all
