Sweet_Anodyne: I think they just updated the store with the Digital Deluxe Edition, because I remember not seeing it on GOG, but seeing it on Steam earlier this day.
Maybe they had to update game files or something and that screwed with the servers? I hope I don't have to download everything again.
EDIT: I checked my downloads tab and the offline backup installer is seemingly re-downloading the game. I'll update when it finishes whether the game becomes playable or not.
EDIT: Install button is still greyed out after offline backup installer reached 100%
Necro-.475: offline installer installed it to gog games/wasteland 3
i manually moved it to where i have my games and then it showed play.
play button still doesnt work (not greyed out anymore) because it tries to download some patch and gives a e9 error.
EDIT: running the game from the exe worked.
Can confirm that running from .exe at least opens the game, there may be problems down the line, we'll see.
Just so anyone else wants to try this the steps are:
1. Extras tab on Galaxy game page, click offline backup installers (gonna have to wait again if you already tried downloading)
2. It should either be in GOG Games folder or GOG Galaxy > Games folder
3. You should have Wasteland 3 folder, look for WL3.exe and click on it
