We play that unless there is a fallow field available (and you have the technology), any corn covered with timber is not available for harvest.I know the designer says otherwise, but it makes no sense to us (thematically) otherwise.
Even if you can harvest in a forest (!) why would you then have the rule about burning the forest to get to the corn (and anger the gods)?
Bottom line is : play the game the way that makes you happy.
