.map file poiting wrong lines after LESS -> CSS compilation -

i used winless there no option support .map file in version 1.x , version 2.x not functional, decided use koala instead.

i downloaded latest version of koala , have problem less compiler. after compilation .map links styles different places in less files suppose to.

i using chrome developer tools debug css mapping option on.

i importing lot of modules main file looks below:

@import 'modules/general.less'; @import 'modules/icons.less'; @import 'modules/faq.less'; @import 'modules/confirmation.less'; @import 'modules/customization.less'; @import 'modules/radios_and_checkboxes ... 

the results of .map links different places depends if select minified version of output or normal, in both cases indicate's wrong lines. there setup may missed?

finally realized issue happen if have turn on auto prefixes. koala compile less first, create .map file , add prefixes change lines should indicated .map. unfortunately solution fix add prefixes in less files.
