Problem with saved games

I recently brought this game, but have just come across problems with my saved games, in both the games I have saved manually and the auto-saved games, whenenver I load them both my party membership is set to 0 and the threat level of organisations are all reset to “minimal” despite being signficant enough for me to be warned of a plot against my government a few turns before the save.

There was a bug relating to this a long time ago, but it was fixed many versions back. Is this easily reproduced? The threat levels of organisations fall after each attack or attempted attack, so it could be a result of that, but party membership should be preserved in save games.
