Ionic serve not refreshing with app-scripts 0.0.47

I just updated my app-scripts, and now ionic serve does not pick up my file changes.
I ran ionic serve --debug and see this:

(a bunch of tslint warnings, which I’ve been getting all along… mostly unused imports)
[ DEBUG! ] worker exited, taskModule: lint, pid: 18920 MEM: 809.7MB

I followed the instructions at https://github.com/driftyco/ionic-app-scripts/blob/master/CHANGELOG.md

Any ideas about what is causing this, or what I should look into?

I have the same issue.
I tried to update my node to v6.9.2 and npm to v4.0.5 but it didn’t help
