I first saw this bug when I was in Las Venturas Police Department. When I clicked on "Go on duty as a Police Officer", I asked me to purchase a weapon license. I already had a weapon license, and this was not the first time I wanted to go on duty. I am already a rank 7 police and I don't think I was banned from public services for any reason. This bug affected not only me, but others too.
So I expect this bug to be fixed soon because after a bank robber, it's a police officer who earns the most. So please fix this bug as soon as possible.
