Based on the original post, I'm thinking the fall jarred one of the weight rings just a bit out of place. You read about this a bit with bimetals, a smack on the ground, dislodges a ring a bit, then vibe.
I don't have a Rally, but, could you try pushing the rings to see if one is loose? Alternatively maybe reach out to One Drop, explain the situation and see if they can fix it (of course, they may charge you for this service - which is absolutely appropriate to do)
