Voting starts in March for the Drupal Association Board election.
An upgrade of Drupal core from 7.10 to 7.12 causes secondary menu blocks to disappear, in spite of the settings in the block interface. I used drush up to perform the upgrade. However, the menu block did not disappear until running drush cc all.
This issue came up with a Main menu (levels 2-4) block assigned to Sidebar First in the Omega theme framework. Changing the top level of the menu to 1st level primary made the menu re-appear, as did re-assigning the block to another random menu, such as Navigation or Development.
I tried creating another menu block with the same settings, and experienced the same issue.
I was able to restore visibility by rolling back upgrades to core and contrib modules. By adding them back one by one and running drush cc all between upgrades, I was able to establish that it was indeed the upgrade to Drupal core that caused the bug.
An image of the menu block settings is attached.
