When the program exits unsuccessfully, all the data entered is lost

[IshaaanVyas]

First I added an employee

Then when I typed in remove-employee/0 due to an error the program exited (already created a separate issue for this error)

Now entering the application again, the employee I had added before is missing.

(This occurs with all other commands as well, didn't want to create a separate issue for all those)

Items for the Tester to Verify

:question: Issue duplicate status

Team chose to mark this issue as a duplicate of another issue (as explained in the Team's response above)

• [x] I disagree

Reason for disagreement: My issue is that all the data that I have saved in the application is completely lost when the program exits with exception.

The issue marked as original is that remove-employee/0 causes the program to exit with exception.

The only similarity between both bugs is that we are causing an exit with exception by typing remove-employee/0 however, my issue is regarding the fact that when I restart the program, all the data that I had previously typed in is lost. This is because data is only saved when the program exits properly and if there's a force exit then data is all gone.

:question: Issue type

Team chose [type.FunctionalityBug] Originally [type.FeatureFlaw]

• [ ] I disagree

Reason for disagreement: [replace this with your explanation]

:question: Issue severity

Team chose [severity.Low] Originally [severity.High]

• [x] I disagree

Reason for disagreement:

This cannot be low severity, this can occur very frequently especially cause the remove command itself causes the force-exit, the user could have stored a lot of data before than and losing it all could mean wasting hours of his time. This causes a major inconvenience and should be High severity.
