Sorry for the delay. The goal is to clear out all earned achievements, but not the achievement types themselves. We want to be able to “start fresh” after a certain period of time, but not have to recreate all the badges and quests. Basically, set points earned to zero for all users, reset the leaderboards, and clear out earned achievement posts.
We ended up deleting rows related to points and achievements from the wp_usermeta table in our Production database, which was scary but worked. A script or function to do this more easily would be most helpful.
