Please describe in as much detail as possible how to reproduce the bug or crash.
Cast Earthquake when any enemy has at least one buff.
Expected: Buff removed
Observed: Buff remains
Suspected cause: It’s removing a random buff out of all buffs instead of making sure to remove a buff that the target actually has. If so, this effect might as well not be present on the spell.
