If i use several Deflector Shields, my HP Gauge 'empties' and shows the HP wrong. I can (given enough mobs) force to show the HP gauge at like 20%, even while i am at full hp. Like you see on the picture (at ~50% HP).

Then the blue bar should overlap the red, or just display numbers. This way i just dont know how much hp i have. If it's designed that way, it's bad design. And if you look at the smaller picture you can see that i have 4818/4866 hp with zero shield (0/0) and the gauge is still at like 30 or 40%
