When in a party, and stepping, the usual gold and experience points don't appear (the icons,) when stepping. I wonder if this was intentional or not, but either way, I don't think this is much of a bug, and you probably won't think much of it. You still receive the gold and experience, fortunately, but it's nice to know what you're receiving when you step, because you sometimes don't get anything when stepping, or just receive one of the two things of exp or gold.
