Necro Skill- Putrid Flesh

[TaraSerenity]

"Spell. Destroy target animated undead ally. All foes near that creature are Diseased for 5...13 seconds."

This skill seems to cause anyone near that animated undead ally to become diseased, even allies.

It's not a bug, it's the disease mechanic. Are you using this in PVP or against Human Monsters? Then they're spreading the disease to YOUR allies.
