I tried Lutris, Steam and Bottles, the bug with mods on DAI for what I understand is because the EA crap App doesn’t recognize launch options like Steam does so anything that depends on it doesn’t work, I don’t know why but with the Steam version you can pass I think was GAME_DATA_DIR option and Steam launches the game with the mods.
The bug on DA2 is probably EA not giving a shit with older games, the DAI, ME Andromeda and ME Legendary Edition doesn’t have it.
