You should verify the file structure is the same as in the stock game by using Windows Explorer to open the game folders. The mod folder structure should be the same, so JSGME can substitute the modded files for the original game files. If you have an extra layer of folders in there, JSGME cannot do it's job right.

I really have no idea what is going on with your game. The problem you describe is something no one else has reported. Most people consider that they are spotted too far away at night.

If this keeps happening, you might want to post some more detailed reports, so maybe we can figure it out.

I can't say offhand what settings I have on my monitor. Most likely everyone will have different settings. The thing is I have mine so nights are dark. If the settings were too bright, it would appear to be twilight to me, but AI crews would see as though it were full night. Obviously, this would not be ideal.
