Let's use an example emote :foo:

If a server owner uploads another emote that is also named :foo:, Ripcord will show both the old and the new versions of the emote when the auto-complete UI appears.

Trying to send the emote code will result in no emote being rendered, but instead the plain-text :foo: will be printed in the message.

Update... restarting Ripcord fixed this issue. Perhaps the old emote was being stored in some kind of cache?
