I found a problem. In the item order, there are two identical items. Harvest only fills the first one, and I can't complete the second one as well.
Also, I enjoyed the game, very addictive!
Ahh, yup, that's a bug I'm working on currently. Sorry about that.
Glad you enjoyed it! Means a lot to hear it. :D
Another suggestion, when hovering the mouse over the plan, say how much time is left for completion.
Sure, that's a good idea. I'll add it in the next update.
