Here it is, a properly redone version. Same instructions as last time, simply paste it into Environmental MOD_2.1/data/Env and tell it to overwrite.
I am very sorry to those who downloaded my last version, but you really need to get this one. My first version took out a lot of really cool effects, that are back now. I only released the first one so that people who really wanted this mod would be able to play.

Edit: This latest version has it all: all of W_clear's original climate zones, weather/water changes when nearing land, and NO CTD.
2nd Edit: W_clear, let me know what you think of this version.
