I now have 3 tribes going in various stages but have noticed that I am having trouble getting tech points for the collective items. At first I thought that maybe time ran out before the kid got it back to the shack so I started watching for that in fact most of the time I collect the item as soon as it appears and still no points especially when I use the younger child not a single credit(will on the mushroom collection) so I started making sure I chose an older child(8-13)and I stand a 50/50 chance of getting credits....any advice.
