I have a feeling its the price you pay for full security, human error can end it. Have used for ages with few issues but just recently had 2 problems.
1) Player sent me the same turn a second time which I did not realise till loaded it, its why you put the turn no on but didnt check so both at fault. Mind you if you dont number the turns & delete the old one as unzip/send it cant happen.
2) My fault completly power cut & my backup UPS is on its last legs so in a hurry to shutdown, out of habit think I pressed end turn instead of continue later, realised the moment I did it but to late. As I had only watched the replay & moved half a dozen units kinda blew it.
Having said that errors are rare I have learnt to check if the phone goes or some such distracting you while unziping, or in your case being crock.

Its also worth bearing this in mind if your opponent vanishes, can simply be a case of getting distracted as he was sending you the file & hence thinks he has.
