ActionMailer::Base.deliveries returns array with duplicated elements in production env

[Tsvetelina Borisova]

Hello, I am testing for email sending from my app and I have a scenario that passes in test env but not in production. When I make dump of ActionMailer::Base.deliveries I saw that it returns array with duplicated elements in production env but not in test env. I am using sqlite3 for test env and mysql for production. Also I use delayed_job. Does anyone had the same issue? Thanks in advance :)
