The IndicatorSprites component will now cycle through all valid indicator icons simultaneously. To make one icon suppress and hide another, use the new 'HidesIndicators' parameter.
When multiple buffs are applied to a part, only one of the buff icons is displayed. You can control which buff's icon is displayed by setting the 'IconPriority' parameter for the buffs. (Defaults to 0. The buff with the highest IconPriority will be displayed.)
Sounds like a reasonable compromise for multiple buffs with same priority
