The Victor OpenDev is appearing in my steam library, but instead of play there is a purchase button in its place. Whenever I click the purchase button on the store page button, I am immediately redirected to my Steam Store Home Page and not the page for the Victor OpenDev. I have Humankind pre-ordered and I also played the Lucy OpenDev. I tried restarting my Steam client multiple times and I have also re-synced my games2gether and Steam accounts several times.

Thanks in advance for any suggestions/help.

I'm so so sorry this happened to you.  The OpenDev only lasted about a week, and closed on the third.

I really wish Amplitude would make the timings on their OpenDevs more clear.

Unfortunately, I have to tell that the Victor OpenDev is over. It was only available for a short period of time.

Steam literally only told us about the Victor OpenDev TODAY... On The 7th...
It's the same reason we never got to play Lucy OpenDev...
There's no time to play it and no warning of when the new OpenDev will start or finish...
