I patched my wine-staging with the patch and it does indeed work.

I also happen to have Heavensward for Mac OS and can confirm if you log in without hiding your wine exports, it will assume you are playing with a Mac OS account, as it allowed me to do all content up to HW as if I were logged in on my Mac.

Hmm, I wouldn't really mind trading my Shadowbringers Windows version for a Mac OS version so I could play on my laptop and my PC easily, but I could see things changing again and I'd need a Windows key again. I never understood why Mac OS and Windows key were separate, anyway. I also have a PS4 key, and it always feels like such a cash grab that I must upgrade each version individually...
