dart not update correctly

[Daijobou]

I use dart-sass version 1.20.2 with this options --no-source-map --style=compressed --watch scss/fileA.scss:fileA.css scss/fileB.scss:fileB.css

In console I see message "Compiled scss\fileA to fileA.css." and filetime is updated.

Now I add a class in scss and again console show "compiled", but in css there is this new class not available.

After close and restart console, its add new class in fileA.css. So --watch detect changes and write fileA.css but without new changes.

UPDATE:
I see that now after restart(console) the file is updated correctly. Its possible that very long runtime(over days) or wake up from hibernate mode(windows 10) is a problem?

UPDATE:
After wake up from hibernate mode its working fine.
