Okay, so I scum - I admit it. I can play actively for about an hour a day so I look ahead a few cookies and see if FTHoF is going to bring about a combination of Click Frenzy and a buff. Once every few days it does so I flick off the switch and settle down. I wait for a Frenzy to coincide with a buff and then FTHoF so I can stack the Frenzy with a couple of buffs and a Click Frenzy.
But recently something odd has been happening. Take just now for instance. There I was, all set up to go but when the Frenzy and the buff landed I went for it and...nothing. The two expected GCs didn't show up. I'd checked a couple of times during the run and the expected GCs were still there, intact. There was nothing I'd done that was unusual but nevertheless, plan shot to shit. Golden switch back on and give up.
So: anyone know what's going on? What factors change the sequence of FTHoF?
