Lulu, first look at a thread just a few lines down called "completely new" by bab006 (I think) and I've given the tip there about watching your researchers at the table and when they give a kick to pick them up and put them back.

It looks as if you may have altered your clock. I did this once by accident and learned from that mistake (I actually forgot to change the day when I was trying to adjust my clock to correct time) and I had similar problem with crop times, though not quite as long as 700 minutes.

Best to play 1/2 speed as this conserves food eaten, although it will take longer for crops, it's a balancing act.

Another tip about mushrooms in case you don't know. You have to take mushroom hunting serious when you're low on food, so keep a sharp eye out and when you spot one, pause game and place all children (youngest/smallest first) on the mushie then unpause, it will help increase food points. It's really helpful when a red mushie appears as they are worth, I think, 45 food points each.

Hope this helps,

Best of Irish,
Maura
