I've recently noticed that whenever I take aggro on GF and get his "fever" the "emotes" will occasionally disappear after the initial 1-2 seconds. This becomes a problem because I've seen other players get confused and walk into me thinking that it's gone. The fever will explode (I hear the sound) and they'll start to display the fever "emotes."

It seems to be a glitch that needs a fix. Thanks devs for your attention to this matter.
