EffectRemoved event not working on party members.

Seems like the EffectRemoved event does not work on party members. (EffectAdded does work btw.)

If I want to keep track of my party members' buffs, how can I do this if EffectRemoved is not working?

Any suggestions?

Unfortunately, effects tracking is broken, and it's not likely to be fixed. Even if you ignore the events and just poll the effects list, you won't be able to get a consistently accurate picture of which effects are active.
