Shop Merchant Problem

When I setup a shop merchant, and leave it for the night I sometimes wake up to find that it closed. I understand there is a 24 hour time limit, but I set it up right before I go to bed. It also happens during the day for no reason when there is still plenty of time left. Usually it will still have 16 hours remaining, but she closes anyways. What gives?

Currently, there's a hack that allows hackers to DC your shop. It was mentioned in one of the threads in the "General MapleStory" forum
