16568	Network install disables site when blog_id is not 1	wpmuguru		"This is an edge case and only occurs when MySQL is configured to skip numbers in auto number fields.

The network install inserts the blog record and allows MySQL to assign the blog_id. The blog prefix logic in wpdb depends on the blog_id of the main blog being 1.

The manual fix for this is to edit the DB and change the blog_id of the main blog to 1. Between being an edge case and a relatively easy fix, this isn't severe, imo.
