Why do translations disappear?

[anabelmd]

I don't know where to post this question or if anyone else has experienced this issue. I had just translated my goal of 40 sentences today and a few minutes later (as I was going through the versions offered by other users) the number was 39. I translated the segment again and was told I wouldn't gain skill points because I had peeked at the solutions. Ok, whatever. But now my count it's down to 35. What happened?

I haven't experienced this, but it sounds odd. Maybe there is a problem with how the site is keeping track of how many sentences you’ve translated. I would submit your problem through the Feedback tab to make sure the developers are aware of it.
