The original AoCQS uses a hack to attach a debugger to the game to launch it instantly. This tricks the game to think it’s running in a development setting. This may have side effects.
You can instead simply create a file “IgnorePatcher.enable” in the game directory, then launch AgeOfConan.exe directly.
AoCQS is basically launching the game in developer mode. That could mean some code runs slower, I don’t know. I would just advise against attaching a debugger to an MMORPG, though I’ve not heard of FC banning for this.
