Nexon ran a MapleStory server check a couple days ago and managed to really foul things up. Trades between players wouldn't work, some players lost a good deal of earned experience points, cash shop purchasing was messed up, etc. I got hit pretty light. Only 1 character(the bowman) lost anything. Just a couple thousand EXP(roughly 0.25%) and some meaningless items. The other 2 were unaffected. Nexon has sorta fixed things by doing a rollback of a couple of days. Not all problems are fixed yet though. Due to all the people who lost EXP(lots lost a few levels worth) Nexon is running a double experience event for the next few days(8AM-8PM). And anyone who's account had any lost EXP whatsoever got a free 2X EXP cash shop card- the 1-day "all day long" card, but coded to last 4 full days. Figure that's about a $10 value. The best part? They stack. Poeple can get 4X EXP during the event with the cards. I got the card and shot my mage from Lv 25 to Lv 30 in about 2 hours.
