Other than the tasks not working for weekly or event, the only other odd thing that I've seen since this upgrade is that I got an ears drop for a character I don't have. (And I"m not sure from what, as it was when I used a gathering spell in the morning to save time.) I think it was for the white dolphin thing under Nemo (that you had to pay for or something, I don't really recall), as it was all white and not Marshmallow. Can't think of who else it would have been for.
Oh, and I just went and counted on my list of all of my LC drops since I restarted 18 months ago (yes, I realize that makes me a little OCD or something, that I have a number of different lists on paper to manage this game and keep track of progress) .... In the first 140 LC that I opened, I received only 8 decorations. In the last 17 that I've opened, I've received 7 decorations. So, it wasn't just me feeling like the game has been terrible stingy lately - it has definitely been bad to me lately. My useless decoration rate (or bench rate, if you like) has gone up from a 5.7% rate to a rate of 41.2%. And I'm not counting trophies as decorations (as I'd happily take a trophy to help with zone upgrades).
And it isn't like I don't have other things available in these chests that are dropping decorations. I still need a lot from most of these collections, like 3 of them were from Frozen - yes, there are a lot of available decorations, but I still need like all of the attractions but 1 and 6 or so characters, so there are other options there. And even if some of the chests with fewer people, I still need a number of them and attractions too.
I know that for most of you LCs are just bench and concession stand after another. But for me, I have a lot of other options, but lately....
