Startup Millenium Achievement

Is this broken? Is that why it doesn’t have an in-progress bar like other achievements?

Some achievements just don’t display progress. “One day” didn’t, yet i still got it after 24 hours.

I’m pretty sure I’ve started Garry’s Mod over 1000 times, both the actual game and going into a map. Has anyone been able to get this achieve?

Just be patient.
It’s not life\death if you can’t prove to people you’ve played gmod over 1000 times.

It’d just be nice to know if it’s attainable or broken.
