Account progress got reset.
So after playing couple games my account’s weapon progresses got fully reset i dont know what bullsh** is this but it makes me pissed off, after hard work its just epic fail now.
Restart Steam, then try and join an official server, see if it re-sets.
Seen this before and it has usually been temporary. It may require other steps to fully resolve but, don’t lose all hope just yet. :)
