Yep, I was just going to report this. It used to drop purple candies (and purple wrapped candies) but the adjusted the level sometime yesterday. I'll bet they intended to remove the purple wrapped candies and removed all purples.
Hopped on this morning afraid I was alone on this one. Glad to know I'm not the only one having this problem too. The first time I played the level the purple candies came, but ever since, none. The game takes forever so I just had to shut it down. However, just for "fun" this morning, I let it run to see how long it would go. Final verdict 1 hour 45 minutes of continual run-time to complete the 25 moves (and that was with me trying to lose). See screen shot for the final stats. Hope it gets fixed soon!
Yep, Got 4,295,600 points on that level! still need 100 purple items!!!! now that's got to be record...I had played it succesfully about 10 times before this bug occurred, now it is always there.
