Not sure if this is the right forum for this topic. Sorry in advance, if it's wrong. Last night our (blackburrow) group frequently got the message relating we had lost 50% or 75% of our exp due to outside players helping us. I don't believe anyone was around our group, and if so only sporadically. We all definitely could have missed something, but to our knowledge we were a lone group. I figured tha if it helped uncover an aggravating bug it was worth pointing out.
