While it works most of the time, it seems that sometimes, Decursive will cast on the wrong target when trying to dispel something.
I was in a group with 1 other person, and when the other person would get a Disease effect, it would correctly show up in Decursive as being on the other person, but when I clicked on Decursive, it would cast Abolish Disease on me, instead of the other person.
I didn't have a debuff, just the other guy, yet Decursive would keep casting the cleanse on me, instead of the person who had the debuff.
What's going on?
