Here is an example of a game which might appear to have broken medals but in fact does not. Check my comment on the game itself to see how to obtain the medals.
This is what I mean by sometimes people are a bit quick to report things as broken because, while yes the medals don't work as they should, they are still obtainable. And simply sometimes people don't read the comments or try enough things before assuming medals are permanently broken.
Specifically, if I notice some problems in obtaining some particular medal(s) in a game, it's not unusual for me to leave a comment to help other people if they read through the comments section of the games.
Again, there is also the unawarded medals section on my profile, where I keep track of individual medals or games I have earned but which the game failed to award. I don't report everything there in this thread, and I actually don't report every unawarded medal there either as editing the newsposts on Newgrounds is annoying. In some cases the medals are buggy, but can be obtained later. I recommend other people also keep similar newsposts if they want to keep track of that sort of thing.
I only report things in this thread if I'm fairly certain not only it didn't award, but it'll never award.
Speaking of which, the Space Manager game has failed to award me the "Space tycoon 500M" medal despite it generally awarding unawarded medals upon reloading the game and letting it run about 10 or 15 minutes or so. Does this mean that medal is broken? I do not assume that yet because it's possible it might award at the same time when I earn the "Space tycoon 750M" medal. I quite simply do not know yet.
However it's highly likely the "Space tycoon" medal in Space Manager is broken as it's the one medal more people have than any other medal, yet hasn't been earned for years. I assume it was probably supposed to award merely for playing the game, but since the medals aren't really descriptive, there is no real way to verify if that's the case or not.
