Harmonix is addressing potential score exploits by wiping the leaderboard scores for Rock Band 4, the company announced today.

The multiplayer rhythm game shipped with "a handful of gnarly bugs, including an issue where experienced drummers can double-deploy overdrive by hitting green 'Overdrive' gems at the end of dynamic drum fills."

However, Harmonix has identified the exploits and are working to fix the issue. The company has to clear the leaderboard scores because the improvements made will affect "almost every song, instrument, and difficulty in the game."

During the fix, Harmonix will adjust the code so that if these exploits appear in the future, the company will be able to "issue targeted leaderboard wipes," instead of clearing the whole thing. The "score fidelity fixes" for individual songs will be launched throughout the spring.

You'll keep your high score data via local saves, and hold on to your 'song plays' stats on the player stats screen. Harmonix also notes that "as far as your song library goes, it’ll continue to display the accuracy and star count for your highest-scoring performances to date," though these will be replaced once you've played the song after the new update.

Harmonix also announced that all scores earned in the Play a Show mode will now be posted to the leaderboards, just as quick play scores are.

These improvements are only just the beginning—in 2016, Harmonix plans on rolling out setlists and practice mode, along with song exports from the original game, Rock Band 2, and LEGO Rock Band. The developer also announced the addition of eight U2 songs to the game.
