I believe that we DC because nexon has implemented some new kind of system that checks for attached hacks after each game, in an attempt to stop people from gaining EXP+GP from their matches. Another theory was that the hacks themselves are causing the DC, because I remember you used to get a hack detected message, you still do when running CheatEngine, which leads me to believe that not many hacks are patched, but the actual game has changed to reject said hacks.
