(00:12) [<color=#FF0A0A>U</color><color=#FF900A>n</color><color=#E9FF0A>i</color><color=#63FF0A>c</color><color=#0AFF37>o</color><color=#0AFFBC>r</color><color=#0ABCFF>n</color> <color=#0A37FF>F</color><color=#630AFF>a</color><color=#E90AFF>r</color><color=#FF0A90>t</color>] Derpsi: Ahh

cant find a option in cofig to make it not try to add the colors to discord chat
