Harvested 45 cows -- Derby shows 43 :(

Yep -- another iteration of the counting bug. I harvested 3 sets of 15 cows. The first two sets went off fine, but from the last set of 15 cows, only 13 are counted in my Derby task total.

I have 45 milks in the barn, 15 of 30 feeds, and no flat or missed cows. I should have 45 milks credited to the task, but I am short 2. I did not notice the game glitch while I was harvesting. I also harvested all cows together, without a pause. I watched the barn counter tick up 15 spots, but Derby counter stayed at 43 :(

Please fix fix the derby -- especially in the time-limited tasks.
