Scripts without file revision history and blank

php

#1

Today I dont know why one of my scripts has been cleared, 0, no lines, and no file revision history to get it back.

In the past, I have experienced it but I just had to close the tab and reopen the file to get it back, but today was different, its worrying me. Had a local backup and it save my day.

There is any issue with file storing in c9?
