For all too brief time (9/4/2018 evening) health bars for me stayed red in the area that was not affected by a hit in combat. Sure the amount I took off turned yellow and drained away, but at least the Red portion stayed Red. Today, this has reverted back to the Red portion turning Orange along with the Yellow portion as the damage is processed graphically. Unfortunately, this makes the Health Bar fairly difficult to read. Getting rid of the Orange and staying Red would be MUCH better.
