Andor's Trail

Hi! I'm translating the game into russian.
I've noticed by chance, that some dialogs, that I've already translated, become untranslated again in launchpad, even without suggestions.
It is not funny to see how your work is lost.
How this could be and is it possible to do something with it?
I'm now saving po file every day, but actually we need to deal with it.

Does someone else ever face it?

Can anyone answer this question?

Well, I still could only repeat the advice: save translation into po file every day after translation session and restore lost translations from it, when necessary. Thank Shadow, it happens only one time per 300 or like that.
