I pre-ordered the digital deluxe edition on steam and I have yet to receive the soundtrack and the tech tree pdf, not to mention the badge on g2g for owning the notre-dame pack. Is anyone else missing the content they paid for? 

Ok, so it turns out I do have the tech tree pdf and soundtrack. I guess Humankind isn't like other steam games and doesn't post the soundtrack and tech tree pdf under "Additional Content" on the game's library page. Rather, for anyone who had trouble finding it like me, you will need to go to properties and browse local files for your game. The tech tree pdf is under the folder titled "Poster" and the soundtrack is under "Soundtrack". Still missing the g2g notre-dame/victor badge though, so any help with that would be appreciated!

I am searching for the additional content too. I have it installed in the epic store but i cannot find any option to gain access to the files. Searching for the humankind files was succesfully but i didn't find neither any tech tree poster nor the soundtrack. Has anybody also have the game bought in the epic store and can  give me advice?

I found the tech tree and the music content under the seam library, but the unit tree is outdated and has false information in it. Will we see an updated 1.0 version sometime soon?
