Hotfix September 9
- Fixed an issue that caused specific set bonuses on the following four item sets to permanently modify a hero’s core stats (STR, DEX, INT, or VIT) each time they were equipped and the hero was loaded into the game:
Please note that this hotfix will only prevent new occurrences of the bug. In order to correct core stats on heroes who were affected by this bug prior to the hotfix going live, we will need to provide a separate patch (for PS3 users) and title update (for Xbox 360 users). We're currently hoping to deploy this patch/title update by the end of the month, and will provide another update once it's live.
