hello all

I am running SH4 1.5 and I WAS running TMO, but kept getting a problem, this being that if I saved and came out of the game in daylight, when I went back in, it was night. This happened two or three times, which was very annoying, even though I started that patrol again. So, just to see if it made a difference, not that I thought TMO was to blame, you understand, I thought I would try a different mod - which I was going to do at some point anyway - and opted for OM.
That problem has not repeated so far in OM, but now, if I Save and Resume, everything is fine, but if I choose Load Game, the game crashes and I have to restart the game to continue.
Any ideas what the problem might be please?
