Refiner's Bargain Keystone + Guarded Hoards interaction

When allocating Refiner's Bargain Atlas Keystone that states:
"Sulphite found in your maps is granted as a random ore instead at 10% of it's value"
And while having Guarded Hoards:"Voltaxic Sulphite veins in maps are guarded by sulphite hoarding monsters"

When killing the monsters around the sulphite nodes, sulphite does not convert to ore.
