Save Game Error Message;
 

I was closing down SH5 last night after a successful patrol with four sunk merchants, saved and then exit. A message window pops up stating my save game failed but was not lost? OK, so does that mean I didn't lose my winning streak and I will be able to start form where I left off? Also, if you select to save off-line (meaning not on the Ubisoft server) is this the same as saving in normal single player games through your hard drive save game folder?
