But, now I wonder, I h ave completed all 6 production options, but the status is still 5/6, how do I know which option I didn't completed?
I had the same thing happen in spite of carefully assigning the different times to 6 different buildings. I ended up having to do the 1-day production over again in a different building. I can only guess that some production buildings don't count for this quest. I set my Sunken Treasures (3 of them) on fp production after I got the quest but collecting them when done still left me at 5/6. It only completed when I collected a 1-day production from another building ( a Blacksmith, as it happens ).
Also, while on the subject of big complaints about the Fall Event, two times now I've gotten the DC chest that gives a 100% chance of 30 forge points. Well, usually it does. Except for now when on both occasions it's given me a baking ingredient instead!!!!
Inno, listen up. Everyone leaves games eventually and it's certain that I will, at some point, decide that I've had my fill of FOE. But it's brain-dead game design decisions like the above that bring that day much, much, much closer.
