Just to add there is no way to effectively stop someone from disconnecting/killing the game and downloading the turn again, it's a built in feature that allows players to regain access to their games in progress in case they do have a connection issue or a power outage and so on.
However, as Bill mentioned all the stats for every upload/download is tracked for each game and for each player, and looking at some of the stats this morning there are definitely players that *appear* to abuse the system. We can't say for sure why players download more than they upload, but there are players that essentially have an equal number of downloads to uploads (fair use of the system), whereas there are some that have something more along the lines of a 70/30 ratio (which appears to be abuse).
Some for example, will have 3 separate downloads of a single turn about 5 minutes apart which doesn't look on the surface like a connection issue, but rather a download, game play, didn't like what happened after a few minutes, killed the game, downloaded again and so on.
As Bill mentioned, these players are tagged and warned by the system, but that aside, if you really do feel like someone is not playing above board, I guess you can ask them for clarification and in the end avoid games against them and play those that you feel/know to play more fairly and gentlemanly.
Would it be possible to make the fact this is logged more transparent to the player?
As it happens I had a power cut just as I was finishing a War in Europe turn last night. So obviously I had to redo the turn.
However the game could have showed me that my average number of downloads per turn had gone up from 1.003 to 1.005 in all time and 1.000 to 1.100 in the last fortnight.
That that would discourage cheat-reloading, just by presenting information that's already been gathered, and without any significant cost to people who are using the turn recovery system for its intended purpose.
Some further steps could be - prompting people to enter a reason why I had downloaded a turn twice or more, and/or making the number of downloads per turn available to other players.
