The lists originally put out were only preliminary lists to see how well they could be split, while keeping to as many people's requests as possible. When time came to finalize, there were too many on the munchkins list and too few on the masters. You were one of the last 2 families to join.....both of which were moved to the masters to keep it even.
The Overacheivers list is not a separate list. There are 3 families doing all 3 lists, as well as some that wanted a master list of all staterooms so that they can do some pixie dusting. That list is for us to look at so it is less confusing. You are only responsible for the families on the Masters list.
I hope your family matter has resolved positively, and big hugs to you if it hasn't.

. Welcome back.......and I have updated your stateroom number on the list.
