I am using the parcel (v2.0.1) localhost server with hot module replacement to develop a simple HTML/SASS/JS-based web app. The HMR is working fine most of the time, but from time to time, especially when making significant changes to the code, ALL server updating stops working -- i.e. not only does HMR not work, but I can't even get the server to reflect the changes by reloading the browser page completely or even stopping and restarting the server. To make sure I wasn't just missing something simple I made changes to the code that would DEFINITELY break certain features and restarted the server, but the page still worked as normal.
I have also tried deleting the .parcel-cache and dist folders and re-running parcel and that has not worked either. Restarting my computer has not worked either. The only mention I've seen of this problem is this github discussion.
Has anyone had a similar problem? Thanks!
Here is the package.json file:

}Put this in your script tag:

Met the same issue: parcel stops working. Especially for me, it happens when I leave a project for day-two and when returned it's broken yet. Even full reinstall (including package.json removing) can't fix the problem. After reinstall, previous broken state is still preserved: it runs recent working code version (I don't understand from where it get the correct code, all data was removed) and doesn't react on any changes except syntax error which cause throwing related errors.
I solved this problem with the following code:
"start": "parcel index.html && parcel watch index.html",
