Damage Guage Does not Cause Automaton to Cure Master

With Damage Gauge on and 1, 2, or 3 light maneuvers the automaton would not heal me. Using Stormwaker and Harlequin head/frame pairs.

I took off the damage gauge and was able to get the automaton to cure me. I was below 50% health. Specifically 44% health. With 2 light maneuvers it cured me.

This behavior is reproducible.

In game name is Velius.
