Hi,
This API:
Fails when you use 0 as a set number. As an example:
https://api.twitch.tv/kraken/chat/emoticon_images?emotesets=0
or
https://api.twitch.tv/kraken/chat/emoticon_images?emotesets=0,1
will fail, however
https://api.twitch.tv/kraken/chat/emoticon_images?emotesets=1
works fine. Only started happening the last few days,
