I'm having the same problem of not being rewarded yarn or buckets. Sometimes I get them, but it takes 10 minutes of trying to get it (this after 10 or even 15 minutes of a timed wait). It gives me the message, but refreshing that page or others and the totals don't go up. I use IE 7 with all the new updates on it. Updates meaning the patches and security updates that microsoft came out with recently.
