no row in userfield table for new users?
 

There are random users on my 3.6.12 forum that don't get a row created in the userfield table when they register. No pattern to it, most work fine but the occasional one doesn't.

When this happens I can't edit the user in the AdminCP I have to go into MyPHP and manually insert a row for their userid.

Any ideas on why this is happening?

Is there a query I can run in MySQL that can insert a row for any users that don't have one in userfield?
