Harmonix today released a title update for the PlayStation 3 version of Rock Band 3. The update provides several fixes, including the Arena 12 Freeze (or the roadie amp loading screen of death) and the glitch that caused corrupted save data for set lists with long band names.
The update, available in North America and Europe, also fixes the Iron Man eyebrow freeze that occurred during character creation. The freeze happened when reselecting the default eyebrow for the Iron Man pre set face. The Pause Scoring Exploit has also been removed by disabling score reporting on any song in which a player repeatedly pauses the game.
Harmonix says it will release another update in the near future to address further issues.
