Hypothetical Scenario #2 - Urgent Action required

This is a voluntary pop quiz.

You're circling in a 30 degree left bank at 3000 AGL.

You hear a sudden change in the relative wind. Both rudder pedals go to the floor. The yaw string is not straight.

Sub-scenarios:

2A The yaw string points to the right pedal (adverse yaw to the left)

2B The yaw string points to the left pedal (adverse yaw to the right)

What do you do next? What just happened?

To derive the full benefit of this exercise, you might respond to this thread with your answer before looking at any of the other replies.

My hypothetical solution is found as a comment below.
