Database export: Error in fights syntax about antlog HOT 1 CLOSED

This was caused by manually setting the created_at fields to null although the schema doesn't allow null.
Providing a default value of 0 for created_at and updated_at in the schema and setting the fields when fights are generated from the double elimination table will fix this problem.
The underlying cause is that Yii's timestamp behaviour doesn't do anything if the table is updated by running a query (via query builder or otherwise), the behaviour only works when the table is accessed via the table model class. So built queries have to manage updated_at and created_at fields manually.
