Not the first time: When an old HSQLDB crashes LO offers to restore the file. I have erroneously pressed "Yes" and the next time the queries and all will be there but the Base will show: No connection to the database. So I close the database file and the whole file will show 0 byte. No problem, a copy is there. But LibreOffice should never try to restore a database file. If I press no I could open the file with the old data without any problem. If I press "Yes" I could lose all data. That isn't restoring, that's destroying.
