"One in a million" server crash #69

Closed ImGrumpy closed 8 years ago

ImGrumpy commented 8 years ago

Server crashed. Log below. Derp says it's one in a million, happens when the "user logs in just at the exact moment this thing checks for things or, disconnects just at the milisecond the pad advances".

Checking the logs, it looks like it also happened on May 12th. Looks like it happened when a user was logging out each time.
