Right after posting the above I gave it one more try and this time the ingredients dropped like they were supposed to. I guess it is intermittently fixed
Thank you Elsa, but it is still not fixed for me as of this morning September 22nd 2018. After I clear the first two ingredients and all the jelly with quite a number of moves left the second two ingredient never appear to be dropped
I have same issue on 9/21/2018. Used a ton of boosters up. Clear everyhing available relatively early on, but the final two ingredients never appear to be dropped
