What is Happening: The Rune of Lichbane's on-hit effetc "Lichflame"deals the same dmg to all targets.

What Should happen: "Lichflame" should deal 2% weapon dmg to non-undead targets and 4% weapon dmg (ie. 2% extra dmg) to undead targets as fire dmg. The double dmg on undead targets is missing.

Ok above are 4 screenshots. First 2 are on humanoids with Lichflame damage doing 10 & 11 damage. Second 2 are on different undead targets. Still doing 10 & 11 Lichflame damage
