Hey

[FakeTruth]

Water IS generated, but I guess it's pretty rare... the generation algorithm definitely needs some modifying.

The water plugin simply makes water flow. The messages are not errors but warnings, because it does use deprecated functions like.. each tick

Here's the water plugin edited by me, to remove some logging and fixed deprecated warnings. This is NOT written by me, but by the awesome guy that goes by with the name ker on the Ae forum http://ae-c.net/viewtopic.php?f=14&t=261
