Why has my local delivery option suddenly stopped working?

Hi. I had all set up a local delivery in radius of 10km of my location, regardless of the purchase value and it worked fine. But now, out of the sudden local delivery doesn't get offered to the customers anymore and they only get General shipping rates (0,00-39,98€ = 4,20€ & Over 39,99 = Free). Anyone has any idea why this could happen? 

My theme is Studio 13.0.0. Is it possible it's due to not being updated to Studio 13.0.1 ?

Thank you.

And as it stopped working without any logical explanation it started to work again without any logical explanation. Might be one of the Shopify's buggs.
