row-cols-# (where # is greater than 6) is ignored

[awbottrel]

I've found that row-cols stops at 6. If you try row-cols-7 or greater, it will just be ignored.
Curious if this is a bug or something I'm misunderstanding about the grid. Is there currently a way around it (still using row-cols)?

I'm guessing you will need to customize the sass import by changing this variable:

$grid-row-columns:            6 !default;

However this is not inlcuded in grid documentation
