I'm having this same problem still and as far as I can tell this would solve my problem. Where's the GustavDev folder located? Hey there! If using Steam, you can right click the game, go to Manage, then Browse Local Files. From there, select the Data folder, then go to Mods. There you are! GustavDev is right there. To recap: Steam > Baldur's Gate 3 > right click > Manage > Browse Local Files > Data > Mods > GustavDev I hope this helps you! Having the same problem with a friend of mine. That GustavDev folder has two folders inside of it that are empty.. Data\Mods\GustavDev\Story\RawFiles then no files. What contents are you able to share?
