I don't think you're reading the things that I'm typing. I am aware it doesn't make sense, that's why I'm trying to get help for it. It's in my library, I payed for it, but it still gives me the "Buy now" prompt. As you can see from the images I have attached:
1: I am in possession of the game, as it is in my library.
2: the latest version of the game I have access to is the .75 version of the old build.
3: In the devlogs, which as far as I've been able to find are the only places where test builds are published, I am not able to download the rebuild version 0.803.
If you're aware of another place to get these files, please let me know. Otherwise, don't accuse me of begging for freebies. If I purchase a game, I should be able to download its updates.
