This is simple.
People who were using Neverborn's\Dark Byte's speedhack.
(Before it stopped working)
Did you ever get the Nexon Message; "Speed Hack Detected. CA will now close?"
Do any bypasses work for you now?
I received this message and though I would end engine.exe, I believe Nexon still got the report.
Since my PC is linked to hacking, did Nexon block all bypasses from it via Hack Shield?
