Potential bug

[Shadow]

For those of you not familiar with the half-land theme, it is prone to land discrepancy errors because of the way the code records free land. Today I had a land discrepancy and it led to some odd behaviour, namely, my food income was NaN (Not a Number) and I was taking desertions even though I had plenty of food.

If anyone has something similar occur, please let me know, and try to keep track of what you were doing at the time it occurred. I can't see any reason in the code for NaN to appear there, so it must be caused by a combination of things.

If it happens to you, let me or windy know and we can fix the land discrepancy.
