My basic farm was set on fire just as the food grew causing it to become cooked and glitch. As a result I can no longer pick it up, only examine the basic farm. I can see the item over the top of the farm.
Have tried picking it up from different angles, to no success.
Had to destroy farm to pick it up.
Whist fighting Bats (Day 12) in a Hamlet. Guards set fire to a bat, killed it. The fire then spread directly to my basic farm and cooked the just formed food. As a result I can no longer pick it up, only examine the basic farm.
