404 Not Found for some emoticons

Some emoticons are not showing for me (e.g: Keepo, FailFish, EleGiggle).

I went as far as analyzing the html which is the following:

<img class="emoticon ttv-emo-4339" src="https://static-cdn.jtvnw.net/emoticons/v1/4339/1.0" srcset="https://static-cdn.jtvnw.net/emoticons/v1/4339/2.0 2x" data-id="4339" data-regex="EleGiggle" original-title="">

and noticed that if I try to open the image url directly in the browser I get a 404

If you notice the URL, that’s Twitch’s CDN. You should be contacting them about this issue.
