OH MAN!!! Now I am really discouraged!!! I am in the same boat...except my population has been maxed out at 100 ( still need 2 butterflys and 2 stones) and I have not been waiting as long as you have, it has been about 5 days with no new collectibles!!! UGH!!!! I started 2 new villages and only "check" in on my old village occasionally now....I will probably NEVER find the remaining collectibles like that. I wish there was something we could do to make them appear!!! I HATE THIS!!!! Sorry...just had to vent...
