Changes only applies when save main scss file.
Other files with underscore (_partials.scss) not watching.

Hi @yaroslav1994,

thank you very much for filing this issue.

Could you please provide more information about the circumstances of this potential bug?

For instance, does this behavior only apply for scss files or are other types of files affected as well?

I'm afraid, I'm unsure whether I will have the time to look into this issue in the near future.
Because of that, I am going to open this issue for Hacktoberfest contributors.

If you or anyone else has the time and knowledge needed to further investigate this bug and submit a PR to fix this, I would be really happy.

Thank you so much in advance!

Best regards,
@jr-cologne

Hi @yaroslav1994,

thank you very much for the clarifications.

I quickly tested this and it indeed looks like incremental builds cause that changes are not taken over to the dist files.

Unfortunately, I'm not sure how to quickly fix this issue.
Since I don't really have the time to further look into this, I'm hoping someone from Hacktoberfest can help out here.

I'm sorry you might have to wait some time for a proper fix.
As a temporary solution, just stop using incremental builds by removing the since property entirely as you already found out that this fixes the issue.

Best regards,
@jr-cologne

Quick update on that issue:
gulp.lastRun() does not work with Sass as we would expect since only timestamps of files without the _ in front are compared to the current timestamp which is why changes in Sass files like the partials are not reflected in the built CSS files.

We might be able to go around this issue by using a package like gulp-cache which seems to compare actual file contents.

Another option might be trying to make Gulp check timestamps of files with the underscore as well, but I'm not sure whether this is possible somehow.
