They disappeared for me too! Do you have a mac? I think that might be the problem or just a glitch in certain computers. They could also be just taken off; I think people were misusing the offers and opening them then closing them and reporting a problem.
Aunt Jodi and uncle Kevin were taken off the show because they asked to be paid for their appearances and Kate didn't think that was a good idea. Beth wasn't really taken off, but because they moved, they live too far apart for her to be in the episodes.
Some of the things i would have taken is a shovel, pick or pan(defending on what i want to do to find gold), clean clothes, a few food items, tent, sleeping bag type thing, a billy, water!, that is all i can think of at the moment.
