Is the update going to be compatible with current save games, or is it going to be a restart and wipe the slate clean affair? I want to know because I kind of want to get a save prepared in such a way as to be in the perfect spot to immediately access the new stuff, but if the update is going to be incompatible with current save games, I'd like to know so I don't spend time doing that for nothing.
My aim is for existing save games to be compatible with the new update. I have a function that patches saves when loaded to add all the new parameters needed.
To be on the safe side, I recommend exporting your data (via Extras) before playing the new update (when it's released). Then, if your save files don't work, you could send me your data file, and I could get it working or figure out what went wrong.
