I just installer the update for Linter 1.0 (and Atom .211).
I’m editing a SCSS file, I love the way the errors are now flagged in 1.0 but the errors persists even after corrected.
For example add !important
to a rule, get a warning. Remover it. The underline remains, and the error is in the status bar.
I needed to do major editing in that region to force a re-lint, and then it went away.
