I made an extremely simple script test map. Small hill, small pond at the foot
of the small hill. On Edit map, the water is there, on Test map the water is GONE.
The settings (tab/tab) for water looks to be turned off by default.
If random users aren't aware of this, they will either report a bug or just assume
GG is not working. And there will be many questions here on how to fix--
well at least maybe! Just reporting.
