Hey, sorry for the delay. You are correct to assume that the resolve doesn’t work in your case; it tries a multiple import. A wrong folder structure could cause this problem since we are using relative paths for the alias (we have to since semantic-ui-less does the same). Because i can’t properly debug this, i decided to upload a full example in the following repo:

Try and see what you might have done differently and please get back to me with any updates.

Cheers! :)
