Gottit.
No idea if this is because of the update or always been an issue, but...
The team I have in Expeditions all had 20XP last night. Now they have 3XP.
No idea when, how, what I did. It has just dropped like it was doing before with the Outerworld team before. I'm guessing it's the same or a similar issue, but I'll leave it in the hands of the experts.
Do you enjoy figuring all this stuff out or do you spend you evenings swearing at your monitor and threatening it with a hammer?
