I don't think this is exactly a bug, but I'd like to know the correct way to replace this method that disappeared in the latest version.
Here's the code snippet I was using it:
// Make sure the data is up to date
bool statsRequested = _client.steamUserStats.requestCurrentStats();
if (!statsRequested) {
throw Exception("Failed to request current stats");
}
int achievementCount = _client.steamUserStats.getNumAchievements();
