Openplant Crash - Delete all piping Components Inside It

HI ,

I am trying to find if something similar come across anyone of us with OpenPlant [08.11.11.304],

Recently a crash happened to one of our user and after selecting abort and re-opening the file, file become blank [ I mean completely blank],

There were not a single piping component inside it, all attached reference were deleted as well, only remains was list of layer which we create for each pipeline,

User was working on that file from 8 weeks, we do rely on IT backups, but please share if anyone had similar experience with OpenPlant,

And if someone found something about it.

Regards,

Vivek
