This is most likely the heRO patcher if it's a custom item that's doing it.

You can also try to go find the "neoncube" file (open it with wordpad) and this file should have nothing but 1 number. Change the number to 100. Save. Open heRO patcher again *while the game is closed* and let it patch. Do not start the game until patch is completely finished.
