All this is true, but as I remember, someone here mentioned (even before the release of 0.8) that theoretically the number of exported saves is not limited to 8 data sets, because the first set of 8 pieces will still be re-saved in the Season 2, which means that if the player at the end of 0.7b accumulated more than 8 different sets (saves), you can safely repeat the procedure of exporting 8 more safes (data sets) from the first season to the second season. And in this way the data export procedure can be repeated as many times as you like.
