All my save files seem to have disappeared. I remember this being a problem with ACII as well, and it has everything to do with Ubisoft's stupid ass Uplay service. I remember playing offline fixed the problem in ACII, but that doesn't seem to be the case here.
For those who've had this problem (I can't be the only one), is there anyway to get my save files restored? Probably not, I know. Anyway to avoid this issue in the future? I might just have to attempt to return the game, which is a shame because it's quite good otherwise.
