Comment 4 for bug 952960

I believe this could be when a economy is separated somehow by the water - maybe because a flag was eaten by water or so. And maybe the economy code does not deal properly with this.

As the flooding code is random, it could very well be that this only happens sometimes. One could come up with a simple lua test scenario that simulates those conditions - I was dreaming about a Lua driven end-to-end test suite for a while now, we might make it happen now :).
