I dunno HJ, I never got this problem of night being turned to day outside of TMO - but I don't think I should blame the mod - lots play it and THEY don't get any problem. I think it IS to do with saving and reloading that save when getting a ship lined up for attack - something doesn't quite go right when I go back in. As it has only ever happened in TMO, and I don't have a solution, the simplest thing is to come out of TMO. I have always played that way ( save at a key point so I can go back if I don't like the way things are going), from SH3 on, and not had any problems before. If I were as good a player as many here I probably would not feel the need to adjust my approach, or whatever, but I am not, so that is my only solution.
