Still loving this game. And loving the humor the developers have in their update posts. I'm surprised they aren't tired of all our "no offline progress" comments. I still have faith in yoU, Ryan!
If you get the error of not having enough tables for pre-production, even though you DO have all the tables:
I fixed mine by building a whole new separate room with a door and all and putting the tables NEXT TO EACH OTHER. THEN they all started pre-production.
finished! at last! the trick to the game is to plant as many trees as you can, because that's the only way to get gems. And try to keep everything organized, like I have an entire area filled with trees. And if you have a tree nearby you don't need flowers. the animals will just eat fruits.
Have fun!
