Try replaying the turn from a previously saved game point and see if it crashes on you again (or not).

If it does crash again, try attaching a save game from immediately prior to the crash event and then we can have a look at it and see if we can spot the problem.

Otherwise a message saying "it crashes!" is not particularly helpful in and of itself.

(One thing you may want to do is to do a disk check with Windows disk maintenance utilities and see if there are any lost clusters that need recovering, those can lead to a file error (and hence crashes) - and if it is your save game, that could be why...). If there were any lost clusters - then probably best to redo the turn from the last save again in case of that.
