If you look closely, there is blueish transparent line after health bar, sometimes it half-screen long, sometime it's short. Cannot seem to find what triggers it, option "Superstyle" is off, combo points on nameplates are off too

Also some wierd icon appears near targets

From what I could tell, it looks like it's related to mobs that are not part of any quest objectives that get a blue bar like that. If they are part of the quest objective, then there is either a question mark or a number.

I haven't noticed this happening in my UI, though. I'm running the latest dev version.

So the weird icon on the right is actually: This mob is a quest mob. If there's a number, that's how many you have to kill/collect from for a quest. If it's a ? then we can't tell how many are needed (usually because you've already killed enough)

The glitch, that's another matter... I'll look into that. I don't get this so I might need more info.

For a start:
a) Does this occur on all characters or just one or two?
b) if the latter, which class(es)?

Oh, I see. Should have seen the connection between the icons and the mobs related to quest.
Currently playing only on one character - mage. It seems reloading UI fixes it temporarily, but after some time this weird blue bar appears again. Still havent found a trigger for it. Just a hunch - maybe it's related to absorb bar.
