That's wrong information. It only happens if you load and save to a new slot or overwrite a different slot from the one you loaded from repeatedly. If you stick with one save game you will have no problems. If you create 1 new save game per day you can play 45 days until the problem will occur.
If I'm not totally wrong - which I doubt because I deal with this issue since days intensively - you can start all over if you follow the rules. You could even continue with an older save but you have no spare saves then.
And just to underline my arguments: I started a new game and din't run into any problem after saving and loading 45 times. That's because I only use 1 slot. bad if you want to go back to an older state but well - that's what we have to deal with right now. A friend of mine has even more saves (like 15) and saved/loaded more than 45 times without problems. As long as you don't save and load 45 times in different slots you should be fine.
Examples:
Save strategy which works
Save strategy which will fail sooner or later
