Unfortunately, this behavior is related to a bug fix, and will affect all stacks. You previously could not BREAK stacks to split them up if you wanted to share with friends.
However, I don’t understand the in and out issue. You can redeem them all, though one at a time, before moving in. The climber and explorer require you to ask them about access to be moved in.
