One round the detective was different than what it actually was for me. The person who actually was the detective looked innocent, and a traiotr(probably could of been anyone in the glitch, but it ended up being him) looked like the detective to me. I thought I was rdmed by a detective, and was even further baffled by him burning bodies, and placing c4. It turned out he was a traitor, and this was some sort of visual glitch. Any ideas? lol cause I don't feel safe by detectives anymore. xD If you can understand..,
I was on the same server as you. That was a custom disguise item, as it took a person's name along with their title (Innocent/Detective). Honestly frustrated the hell out of me for the most part since I had no idea it was on that server until I left (only grew slightly suspicious when I was being shot by Innocs/Detecs at random times, figured people were just being dumb).
The only solution: Play on servers using the official versions, I figure. The last server I was on had an item that actually checked for weapons from a good distance away. Lasted three rounds before losing my mind after detectives kept spotting C4/Flare Guns like it was a life-threatening disease.
