Menu blocks in the login menu - IMPORTANT!

The login menu uses blocks within the menu block.  The module that does this is menu_inject_block.

The module has a bug that disables the injected blocks if a menu item is moved or otherwise edited.  (See https://www.drupal.org/node/2001518.)

The fix is, after menu items are moved and edited, to reopen the menu item that is not working and re-inject the block.
