Well … after reading this thread , I’m less and less sure that it’s hackers/exploiters and tend to think that … it’s peak funcompetence . I mean … if this can happen in a single player game , where there is no possibility to be hacked … why would it be hackers on servers ? 
Edit for future readers : I’m not saying their isn’t cheaters/exploiters on official servers, I’m just saying that some of the reports that has been attributed to cheaters, like the reseted skills / knowledge and other issues that was potentialy attributed to hackers may just be bugs. I’m not even discussing the fact that some cheaters have accessed admin level of control on official servers ! ( I saw the hole blue ranger debacle )
