Explain retainer exploration ventures to me... You need 15 in a week, quick explorations don't count and to send a retainer on 2 takes longer than a day. So, even sending 2 retainers constantly on long explorations, you can't complete this unless you pay for a 3rd. I did it only for extra storage, but making this goal require you to make the extra retainer purchase to complete is really sketchy to me. I agree totally that this needs a fix.
