in this stuff I HAVE all 3 expansions, after this action: replace Mystic Vale\steam_emu.ini with Mystic Vale\Mystic Vale_Release_Data\Plugins\steam_emu.ini (in which exists all 3 expansion codes in [DLC] section)
Replacing the steam_api64.dll with the steam_api64.dll._original (renaming it) makes the game work (the only thing is that the Leaderboards button is no longer accessible).
replace Mystic Vale\steam_emu.ini with
Mystic Vale\Mystic Vale_Release_Data\Plugins\steam_emu.ini
