Can someone hack an invetory item that you are wearing? Suddenly 2 people managed to get on my open collar that i never even have heard of as secundary owner and i have no idea how that happend. (it is just me and my partner that is on that collar as orimary and nobody else which was about to skin me alive) I have two idea in my head 1: Someone hacked one of my items (my collar for example and do not ask me how that i have no odea of at all) 2: Someone got added by using a RLV trap or something.(again i don't know how that can happen) If someone knows one of these 2 options is possible pease let me know either positive or negative.
