Stdlib docs - all links to source code is broken

For eg. go to https://nim-lang.org/docs/system.html and try to open source code of any variable or proc. The github url is 404. Apparently master branch does not exist anymore.

Ugh, that's bad... Something happened with master branch (it was deleted by someone it seems).

That's too bad! Any idea what happened?

master branch was re-created, thanks @NeeleshChandola for informing!
