You guess it: known problem. The assert is there since I had problems
with the calculations long time ago which hinted that irrigating a
city center is a good thing. I fixed the bug but left the check
in. Now however it is also possible that the irrigating changes the
terrain type. And this is valid and may make the tile better.
