Team's Response

We agree that this should have been handled gracefully, however, as discussed here: https://github.com/nus-cs2103-AY2021S1/forum/issues/423, we have chosen to lower this to "low" for the following reasons:

• Only advanced users are expected to edit the JSON file, as such this should be a rare issue since most users are not "advanced"
• If a user is already "advanced" enough to edit the JSON file, it means that they wish to place a MC value of their choice. MC values are known to be numerical and no user would reasonably input alphabets. As stated in our UG:

• As mentioned in the forum post above, users can revert their change and still continue using the app normally
