In the experimental version, I observed new weird colors during sunrise and sunset. Normaly (my base is in the grassy fields) sunrise and sunset appears to be kind of purple. I played the non experimental version for many many hours, and it always was the same. Now (experimental) everything is more greenish when the sun comes up or goes down. I think (but can't say for sure) it's not always this way. It could be different, when I restart the game. Must validate that...
