Just as in 1.0.2, save files will still end up corrupted if you reload and save enough. From my personal testing, I reached 45 reload-save cycles before future saves become corrupted in 1.0.3 (as opposed to the 35 in 1.0.2). I would put the game on hold until they address this again.
If you didn't notice this in the previous versions, it's probably because you didn't reach the number of cycles before the save file became corrupted - but trust me, it was there all along.
