When in the ACP, there is the option to delete a user and all their
posts. This would then call the user_delete function and define $mode as
'remove'.
On lines 485-521 was some code that would delete their topics, then
after that there would be a call to delete_posts - which would also
delete their topics. It would not update the board statistics, and the
thread count would remain the same, even though several had been
deleted. It stopped delete_topics functioning correctly, so
delete_topics would not update the board statistics either.
My solution to this is to delete lines 485-521 and allow delete_posts
to call delete_topics, thus updating the thread count in the statistics.
