The game does have some dates and assignments "off", to say the least, but also, with Saved games, you can really run into some weirdness if your mod load-out does not match the old Save file. In other words, if you had TMO and RSRDC previously, and only have TMO now, but load a Save from the TMO / RSRDC combo, things may or may not work initially, but you are guaranteed to run into trouble eventually.
