I got a Drupal 7 feature, which contains certain Strongarm variables, such as admin_theme. This feature has been created, released and reverted multiple times, always without fault. Suddenly, the last feature revert leaded to a deletion of some variables which are clearly defined in Strongarm.
The only thing that helped "a bit" was to remove the variables from the feature, release & revert them, and then add the variables again and release and revert once again.
This can't be a solution for the production release because this one has to work in one time. Why can it be that a Feature revert deletes variables from the database (variable table) which are clearly stated in the feature?
