Appears Diablo IV and Overwatch uninstalled themselves. Last played Overwatch two hours ago and Diablo IV last night. Instead of seeing a Play button there’s an install button. Searched for the installation folders but both of them are missing. However the folder in Documents are still both present. Other games that I haven’t played in a while (Diablo III/Starcraft II/Heros/Heathstone) are still installed.
