Shattered Kingdoms

So currently, you stop gaining xp once you reach GM. Or atleast shortly after it and only gain more xp if you get rewards and so on. But I noticed the familiar code is still active after you gm, and even though you don't gain more xp, an area will go from discover all the way to you need to get out. Which doesn't sound like a big deal. Untill you need to actually get that xp back because you used the oracle or one of the lesser return to the living spells and now that area no longer is available to the same degree for xp.
