Doubtful.
Also MapleStory did do it once, by accident xD
Yeah, I agree it's very doubtful. Speaking of MapleStory...they had no choice but to roll back due to all the scroll hacking that was going on and now with the recent hacks i.e: PG Hack, Duping, Guild Glitch Hack, Fame Glitch Hack...and many others, hopefully they don't resort to a rollback. Just fix the PE hackers fix the loopholes used in the process, update gameguard and just reinstate guild leaders their guilds back and capabilities, it would all work out. If they are smart enough. They have been a huge let down since they took over Wizet.
