further investigating ... if boots and holy symbol are unequipt, then equip one of them, the 20m white light does return ... just weird if you leave boots (20m white) equipt, and equip hammer (10m blue) the blue over rides the boots, and then (third) you equipt the holy symbol (20m white) the hammer still has priority.
But if I unequip both boots and holy symbol and leave hammer equipt, and the equipt holy symbol or boots then 20m white light returns
maybe not a bug ... just thought I would let you know
