Festival hall works crazy, skips productions or buff additions. This time after two cycles instead of 102 gave 64 - which is less then basic production (basic should be 68) without buff although 50 % buff is running all the time. Previously, when I was watching, one of the channels only gave buff boost, not basic amount (6 instead of 18). When I tried donate after each channel finished, all 3 gave correct amount. As it is it's basically stealing about third of my production. This way the event is pointless.Somebody help me. Don't want to hassle with support. It's only 2 weeks event.
EDIT: Checked another cycle, instead of 51 gave 39 - skipped basic production (12) of one of the channels.
Edit 2: Next cycle gave 34 instead of 51, which is exactly basic production without buff boost (buff still ruining with over 4 hours left)
So it's intermittent bug with no logic at first sight.
