Save game error

[DS]

I looked around and couldn't find a thread dealing with this specific problem, though there were discussions about a similar problem with using saved maps. Sometimes I just get a message saying that the game can't load, other times it tells me that there is an access violation at module such and such that reads at FFFFFF. Now that I've tried running this game some more it appears that the problem doesn't occur randomly, but instead at some point in the game, after turn 114 the game is no longer able to save properly.
