this morning the 3 day calendar disappeared from the carousel in all my games,I lost an hour which is 2 boxes each , before I talked to a friend who showed me a way to get to it, Not good. Now I never have to use the interface for anything. it was there at approx 5:10 am EST then disappeared and it still not there,and it is 9:16 am EST,
I'll be sure to check with the developers about it to ensure this doesn't happen next time. In the mean time I'm sure Support can help sort you out.
