nth-child not support

[vincehi]

.class { &:nth-child(3n + 1) { } }

After scssfmt :

.class { false { } }

nth-child(2n) works
nth-child(2n-1) works
nth-child(odd) works
nth-child(even) works
last-child works
first-child works

nth-child(2n+1) does not work

It looks like the error only occurs by using a '+' sign.

@souricevincent in your case you can use the next line:

.class { &:nth-child(3n-2) { } }
