Hi, after days since the launch of Space Age, i found out (thanks to the great people on the factorio subreddit)
that my game is "soft locked" i got to the space platform and build it out some tiles. Then i realized that i can't find or make asteroid collectors and the crusher building. and i guess it comes from this mod. in your screenshot you have toggles for different stages, Yet in my game i only have the first one "

By any chance did you type "hide" in the ctrl+f bar thinking it would show all options from any mod that matches "hide"?
Sadly it doesn't match by mod name, only by setting name. I also wish it would match by mod name.
Try "reveal".

Welp thanks , wow TIL.
That is my way i used it the whole time :p

I can also confirm - Space Age asteroid collectors etc are hidden, even after being researched.

I toggled on the "Show Space Age Content" checkbox, and it works now, but it would be nice if this updated dynamically.

Check out "Can the mod automatically reveal things when appropriate?" on the main page.
