This is somewhat a issue @Valorous when you usually add a new daily the .sav file gets "weird" (sorry for the lack of a better term). Probably because you're using id numbers for each daily or something? Not that it's a major issue but if you one day get time to maybe change the way this happens or maybe make the new dailies a higher id number from the last one. Hope it makes sense if not i'll try to explain better through pm
The serializer is getting confused because of a combination of factors.
