config json file is empty (all data is wiped out)

[alishefaee]

I used config json file to save my config. but I rarely sometimes encountered an empty file and I didn't know why.
Until recently this happend when electricity was gone ( or computer is unplugged ).
The config.json file exists but is empty.

"nconf": "^0.12.0"

OS:
Window 10

Hi alishefaee! I know it was a long time ago, but you discovered how to solve this problem?

It is happening to me too and we are using the lib to critical config files.

@mfpereira No, I didn't

This is an old issue and still does not work with example. I think that it is due to memory and format parameters in save function implementation. Just use save without callback function config.save(); will still work.
