The game “Muv-Luv” on Steam was unpublished and republished with a different App ID. However on Lutris the metadata is locked to the old App ID without any way to modify it: https://lutris.net/games/muv-luv/
Old App ID: 449830 / New App ID: 802880
I think the Lutris Steam sync feature merges the 2 instances into the old ID.
Same problem with the sequel “Muv-Luv Alternative” https://lutris.net/games/muv-luv-alternative/
Old App ID: 449840 / New App ID: 802890
Not that big of a deal since the installer script can specify the game ID, but there is still the broken “Get it from Steam” link on Lutris.
