I got lucky pulling a failing seed on the first try.

AUTO INCREMENT causes a problem when some factories set IDs and others do not.
They end up with the duplicate primary key.

1. :proposal_item_configs_expected_participant # id { 1 } is specified
2. :proposal_item_configs_presentation_method # id => 2 (auto increment)
3. :proposal_item_configs_assumed_visitor # id => 3 (auto increment)
4. :proposal_item_configs_session_time, :all_ok # id { 3 } is specified 💥
