Importing my MyBB instance into discourse instance with `SiteSetting.max_category_nesting = 3` fails with this error: ```plaintext creating users 66 / 330 ( 20.0%) [633 items/min] /root/.rbenv/versions/3.2.1/lib/ruby/gems/3.2.0/gems/activerecord-7.0.7/lib/active_record/validations.rb:80:in `raise_validation_error': Validation failed: You can't nest a subcategory under another (ActiveRecord::RecordInvalid) ``` I’m guessing the validator wasn’t written with this somewhat recent change in mind.
