Lockloss again during TRANSITION_FROM_ETMX; the same place as before.

Since the wind is forecasted to die down this evening, I'll plan on holding H1 at 2W in the CHECK_VIOLINS_BEFORE_POWERUP state and engage 2W damping until the wind calms, then try again to get through TRANSITION_FROM_ETMX in case the excess ground motion is what's causing trouble.
