Repro:
- create a new project via
npx create-rescript-app@next
- install the latest version from the actions page.
At the time of writing: npm i https://pkg.pr.new/rescript-lang/rescript@22ad3f5
- run
npm run res:dev
- make a change to
Demo.res
This happens for me on Windows.
I also checked 12.0.0-beta.2
