Second, I want all of you to know how to abuse this feature. Because BUZZBOMB
So here's my little noob tutorial on how-to!
Let's get started.
First you want to look for a village that is built next to a cliff. I haven't found any, so here's a little example of a cliff a village might have been built on:

Honestly, any cliff with corners should do.
Next, you should PAVE the corner so that YOU CAN SPRINT (my friends have confirmed that running sometimes does work, but it takes a little longer time to get used to). Grasslands work too because you can SPRINT on them.
Then, you locate a jumpable corner. Usually any corner is jumpable, and they often require different "spots" to find. Here is one:

THEN, you come AS CLOSE AS POSSIBLE to the corner pixel:

THEN you activate SPRINT and you click AS CLOSE AS POSSIBLE so that you character "twitches" a few times just to get past the cliff:

If you have anymore questions, feel free to ask in this topic and/or on PM!
