Is the rare collectible always one you still need? Or might it be a duplicate?

Any more opinions now that it is 2010 in whether pausing works well for this? Also- is it sometimes a minute or two ? Does the chief leave before the collectible appears? I have tried three times but so far no luck

My puzzles are all solved and other than my plan to have everyone dressed in black and white, black, white, or gray and then two or three in red I am about ready to bid my villagers adieu but need a few collectibles.

Thanks in advance for your help!
