When working on .less files, autocomplete is working sometimes, and sometimes it’s failing to show anything. I tried to record video on screenr.com but I can’t replicate this error when i need to.

Basically what I am trying to do is create new .less file in project I am currently working in and when I save that file and try to write some CSS I am not getting any autocomplete options. Then I need to close that file and then open it again, and usually after that autocomplete is working again.

Is there any other way I can help debug this?
