So, I just logged in, and when I joined the lobby, I received an alert with the message
Congratulations, you have been awarded 4000000$. I have no idea why or how, I didn't do any specific events. The only thing which "happened" was that I have 400 hours on GTA V on steam since yesterday.
Could that be the reason? Or is there some kind of event I missed? Or could this be done by a hacker?
