The servers will be coming down again (written as of 10:54 AM PDT). Due to an error on our part, the button to reset dungeon count was functional again despite that not being intended. As it's a grave issue and some people have reset while others have not (which is massively unfair) we'll have to look into resolving this issue. We'll update you all ASAP on this problem as soon as it's resolved.
