I've been having this same issue every time I've partied up with somebody. What happens is it confirms that the party has been opened, and we're all good... but when one of us kills something, nobody gets any experience for it. I've logged off, reset, everything you can think of and this happens all the time without fail. We can swipe through ten, fifteen, twenty monsters and neither of us will show any change in our experience bar.

I hope this is a technical thing that perhaps I simply missed during the tutorial. If it is I'll be thankful because it happens every time without fail. If anyone knows of how I can fix this or if there's something that needs to be adjusted in the party settings I would certainly appreciate the help.

Thank you.
