It's not that way everywhere unfortunately, I've only gotten 2 ingredients from incidents in 5 days. I managed to switch to harvest farms kits today so won 11 of them and was able to see better where I'm at in grand prizes.
Looks like I will definitely fall 1 upgrade short of the sunflower press despite being active everyday, getting all bonus ingredients from daily challenges (including bonus from the newsletter), and collecting all incidents. This should not happen - that an event building is unobtainable without diamonds.
Sadly I am counting the upgrade kit I'll get from placing top 20%. Players should be able to get the event building if they are fully active.
