Redirection loop for non-English pages that do not exist

[firebomb1]

When visiting a page that doesn't exists the site goes in a redirection loop:

https://jam.dev/c/1a307e82-067e-4f86-8de7-2f175fb12f60

I've stopped the loop in this Jam by pressing Esc after few reloads.

Be careful to not break the rest of the language redirection logic when fixing this.
