With the release of patch 4.0.1, we have noticed an issue which has resulted in all Warlock pets being renamed. Unfortunately, our support team will not be able to assist with the resetting or renaming of these pets. We apologise for any inconvenience these name changes might cause and thank you for your patience and understanding.
For this and all other known issues with patch 4.0.1, see this thread:
