I have 70+ hours on the game in the last 2 weeks and even more in the editor because i've been making a game, and i helped a bit in the community by helping game owners with glitches, for example I helped report bugs for Mow The Lawn, it had about 40 active players last time i played, and now i even own a bunny hat.

How come my access is gone?

Which access do you mean? If you're referring to S&box access, you can build it from source. It’s a bit challenging, but definitely worth it in the end.

I heard that some people got their access back

I’m experiencing the same issue. Ever since I discovered that it was possible to help developers improve their game, I’ve been fully dedicated to doing just that.

Admittedly, I don’t have as many hours played, since I only discovered this opportunity recently. Additionally, I have real-life responsibilities, such as taking care of my sick grandmother or providing for my family, which naturally come first. This means I can’t play every evening or commit to long gaming sessions.

However, out of the 18 hours I’ve spent on the game, I’ve taken the time to communicate with developers, provide constructive feedback, and even dedicate time outside of my recorded Steam playtime to offer help and see how I could contribute.

If this is a mistake, I hope it will be corrected soon.

If not, I find it disappointing to have invested so much effort into helping, only to have my access to the game revoked. If access is being revoked solely based on playtime and consistency, that feels unfair to people in situations like mine. Is it better to have someone who genuinely tests and contributes, even with fewer hours, or someone who simply leaves the game running idle on the menu? That’s the real question.

Best regards and sorry if my english is bad, i use a translator.
