Was able to redeem the Lucy OpenDev, resync my Steam account and it shows up in my Library. However, it didn't ask me to install it and showed the Play button right away. Trying to click it opens an error window of the missing .exe , which makes sense. However, if I uninstall and reinstall it, it just downloads a readme file that says "Welcome to Humankind!".
How can I download the rest of the files?
