As far as I'm concerned, pulling the Fall Boxes, which pay out about 2YC every 50 boxes is outrageous! I even went on to YV forum to complain and my post was deleted! Poof! This is cause for another rebellion IMO. They're pulling all ways to profit in the game....as far as them wanting us to spend real money, it seems? So angry.....AGAIN. No more Fall Boxes. No more free YC. Ugh.

i opened about 1.3k boxes i never got any yocash for fall ones i got about 12 from cottage boxes which they removed

I am not sure why but i do know that the fall theme is rather old so maybe they figured (and I agree) that the boxes were out long enough. I never got any yocash from them sadly.
Hopefully you find some in other boxes.

I have some unopened fall boxes you can have if you want
