Most people only realize the value of viable backups after situations like this occur. Then they face a choice. Start taking responsibility for your files and back stuff up -or- do nothing, complain and blame others.
I have back-ups!
But why should I need them?
If FDev did the job properly, this should not happen.
I mean - we had an open Beta, so quite a lot of people took part.
Then the final release is done, and some random crazy bugs manifest themselves from the get go.
And you think this is a player failure.
Sorry - no.
This is a total incompetence developer situation, nothing else.
