Hi there,
before submitting a new issue, please consider the following:

• [*] This is actually an issue with Leaflet Routing Machine, not a question
• [*] You have read the Leaflet Routing Machine documentation and tutorials
• [*] You have looked through existing issues

In my angular-app I am trying to support couple of languages, one of them is the slovak, I have went through the PRs here and I have done the same, but still I am recieving that the sk Error: language code sk not loaded, I might be missing something, and would like to ask if anybody have been through the same issue.

Best regards
