wpmu dev dashboard repeatedly prompts me to update after "successful" updates

Logged in to wp-admin, was prompted that wpmu dashboard update was available (current version 3.3.3; new version 3.4.1), clicked auto-update, went through update sequence (where it said plugin was updated and reactivated successfully), go back to dashboard and it still says my current version is 3.3.3 and prompts me to update to 3.4.1.

checked ownership and permissions on wp-content/uploads and wp-content/upgrades; both are set to my user and 777.
