January’s Darkmoon Faire achievement progress status was cleared prior to the launch of February's faire. Any achievements that were started but not completed have had their criteria reset. Completed achievements are unaffected.

However, any future achievement progress (February included) will be saved to your character and will continue to contribute towards progression of those achievements in subsequent visits to Darkmoon Faire.

Regrettably, we are not able to restore any progress you may have made during January's faire. We do appreciate the impact this may have had and sincerely apologise for any inconvenience caused.
