a bug occurs whenever you escape or die in the core explosion and results in the yellow race box at all races disappear
this bug happens sometimes
this bug happened on PC
in order to execute the bug all you need to do is escape or die in the energy core explosion then whenever you go to a race hub (dirt track for example) the yellow box that you enter to start a race dissapears
this bug only appeared for me but might appear for other players in select cases
