So I tested the solutions... So I'm going to validate the answer already.
It seems that what happened these are that the coin planted at my colleague's house the day before and suddenly, all the family of coins was made metre by piece at the same time.
So I tested the recovery system of the part family with the 7-Zip program, and I could see that she was no longer present in the room... As a precaution I looked at another coin with a family of coins and you can see it clearly.
In the end, my colleague was able to recover the part from before the crash, going back with the daily backup that our computer scientist had.
I remember any answer in case the problem comes back;)
