This problem made it to live. Pretty much makes the addon unusable. Your health will decrease and the numbers and percents will be accurate but the graphical portion of the bar will not change until you switch targets or your target dies. At which point it will update the graphics to reflect what it actually should be.

This is the only horizontal stand-alone health/mana bar mod that I could find. But I am unable to use it unless it receives an update.

On the PTRs for 2.1.0, TakHud is broken so that the bars do not increase/decrease properly. For example, while taking damage, the player bar will not always decrease. The numerical health values will tick down, the health bar will even recolor itself like your health is getting low but the bar itself will not always properly represent your current health percentage. It's not a combat thing either because it will periodically snap to the correct level while in combat but will then 'stick' again.

Are you looking to add pet health & focus bars anytime soon? I love this mod, as it reminds me so much of StatusBars which I was sad to see fade into not working, but I really miss the pet bars on my hunters.
