Day 2 just ended and I had 390 blankets (and about 3 seconds later 394). So still on track even though I started with only 1 large farm and have upgraded 2 more having them not producing food for 16 hours during the upgrading time. Very happily surprised!
Unfortunately I'll be working when the event ends so not sure if I can make it to the last prize, but I'm very happy as long as I get the Meadow dragon which is my favorite one of these.
