Well - it's an auto incriment field - so it shouldn't happen, but what happens is people don't quite follow the instructions and end up registering a user in threads, rather than just importing. So the user #2 get's used before the classic import starts.
If you nuke the Users table- (empty it out) ... make sure you leave user#1 (the DONOTDELETE user - this is a placeholder for anonymous posts and users who have been deleted. Then reset the auto-incriment number, so the next user created would be user#2. Then the first user classic imports will be user#2. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
the problem that usually causes it, is that the user number doesn't get re-used, and people install threads, create a user or 2 before doing the classic import. I think the classic import instructions tell you not to register a user under Threads until after the classic import.
But if you write any scripts to fix it that you'd like to share - the place to post them would be
