I tested this the following way:

yarn preview:hbs
cd packages/development-edition-engine-handlebars
yarn pl:serve

make change to source/css/pattern-scaffolding.css

changes are not reflected in the running app

I just reproduced your test with npm run pl:serve and yarn pl:serve on windows. For me it is working. The problem maybe is, that this isn't written in the console, because chokidar.watch() doesn't say which files changed at that point. You can turn this on when you add logLevel > 0 to your patternlab.config.serverOptions. (That behavior was implemented before)

If you change something in source/css/pattern-scaffolding.css you will notice the browser reloads. To be sure with this test you could try to add something like this.

body {
   background: red;
}

@JosefBredereck i apologize - i tried pulling this fork locally a new way and as it turns out, I had NONE of your changes 😊

This now is working for me too - tested on Mac and Windows

@bmuenzenmeyer do we close the tickets accordingly?

[bmuenzenmeyer]

they should auto close when released - if you dont mind waiting for that
