I followed the instructions to setup the divinity engine on Steam per: https://docs.larian.game/Setup:_Editor_Steam
These apparently ARE NOT the correct instructions for definitive edition and you instead have to select this path: C:\Program Files (x86)\Steam\steamapps\common\Divinity Original Sin 2\DefEd\Data\
I can't get back to the initial setup where it asks you for the file path now... I tried uninstalling everything, restarting and reinstalling everything, but I still can't get the prompt asking me for a file path. And could someone PLEASE change that setup page? Definitive Edition has now been released for exactly 2 years, but they never updated that page...
