would saving with the no spawning in effect cause problems? because about the only time of day that seems normal is night. all others have no spawns or very few. (i've never used any of those added times and don't even know what they look like)
In what version did this strange spawn problem start happening? I have v.44a and it seems fine. Maybe you could have 2 copies of each version? One with Alt TODs and one without.
Oh, you have it. You just haven't noticed yet. The issue actually started in .43. It's the standard vanilla sunset timeslice that's the problem. Anytime your game starts on sunset or you finish a mission and it changes to sunset is when it happens. I had to go back through all my saves until I found one that loaded sunset and was able to confirm it 100% of the time.
