Non-localized feed field

A very minor bug, but I'm noticing that while much of the news feed is localized, the "reward" field is not.

Example:

achievement: {
id: 2144,
title: "Ha sido un largo y raro viaje",
points: 50,
description: "Completa los logros de eventos del mundo listados a continuación.",
reward: "Rewards: Violet Proto-Drake and Master Riding",


This exists in at least four places:
