[quote=Kyrone]So I registered because I had the same problem and I found a overly complicated to figure out fix that appears simple enough!

1) Open steam console by typing:
"steam://nav/console"
into URL bar which should open steam as an external app and not use your favorite search engine.

2) Type "download_depot 435150 717550" into the console (717550 is the engine data dlc and 435150 is the appid of DOS2)

3) Wait for it to finish download... it takes a while (Took 1 hour for me)

3) Goto "*STEAM*/steamapps\content\app_435150\depot_717550" and copy/cut/merge the "data" folder into "*STEAM*\steamapps\common\Divinity Original Sin 2"

Hey, that worked for me, too! I tried every single other solution on the internet until this one came along.

It didn't bring up the DLC tab, but it added what apparently was missing from the data folder, so I was able to create a "Basic" level and have been editing it.
