The only problem with the Ai that I've discovered is that it doesn't recognize custom monsters. I tested this on other servers as well and same problem Q.Q. The heRO ai is nothing more then the mir AI from a year ago. I don't know why it lags you for when ever I tested things here it never did it. Are you running that config file open as you are on RO? You don't actually have to have that up, and any changes you do you have to restart the RO client anyways.
With your Lif disappearing, you may have lagged badly while going through a mob and she died or they just stayed behind.
' They do that often so just rest and call homu again.
