When the belts came out I did love them still do even if I wasn't going to get a reward each and every time i harvested (as I viewed it), wasn't a fan of how they changed the 3hour to 12 hour on the belt rewards.
I have harvested my flowers and noticed I had a larger amount than had planted, pretty sure not from any reward clicking. As the one I clicked on didn't work when they had the flower reward glitch and may have received the bonus later but it was still more than what the first brown belt bonus was.
Perhaps a sticky is in order (or we can keep quoting jas on each and every post)
