The "Dark Green" mood meter is an indicator that you have an incompatible mod installed in your game.
The effect is due to a mislink between a scripting mod you have installed, and either the Core files or another scripting mod necessary for its operation. When the mislink occurs, it bounces the loadup of the game, causing odd graphical issues and game-play errors.
The solution is to go through the mods you have installed, and ensure they are all compatible with your Patch Level.
If you have any option modules installed, also ensure that you have the proper base-mod version installed for them.
