I noticed this too, and I do hope they correct it for the druid class when it comes.
That said, the 3 lifebars of a moon druid would seem to be intrinsically OP in this game, especially given the low amount of encounters per rest. The rest system is really important to modify and get right to be honest, as its already feeling to me like you can just dump all your cool stuff in combat and then full rest for no penalty, which will tilt balance pretty sharply.
