FIXME: This code is dangerous and needs to be refactored. We can’t just
comment it out, but it needs to be fixed for a variety of reasons. Get rid
of this ASAP!
When a player logs out, their data is queued for persistence in the next
tick of the persistence batch update unless the character logging out is
dead and has hardcore enabled, in which case the character is deleted
instead of being persisted. The player will be temporarily unable to log in
during this period to avoid the race condition of their login fetching their
old data and overwriting the data saved here.
