Workaround for bug #144. This workaround had occurred to me a while ago, but wasn't sure if placing them unfairly was better than not placing them at all. Argument for not placing at all is people should probably abort the game when they notice it. Argument for placing unfairly is people can still abort, and if we really wanted them to abort, we should probably just have halted launch if all hogs failed to spawn. This way at least play can continue.
