Bone King goes free
After a lot of testing the Bone King will occasionally spawn outside of his cage, if you turn him in to the Graveyard Keeper and then leave the area to trigger the world state change. The Ancient Graveyard will be taken over by the Keeper faction, but the process of reloading the town releases the Bone King, for a nanosecond he doesn't have a cage while the world changes. You can simply take him down again and put him back in his cage or take him home with you as a trophy/sparing partner.

I assume it's a problem with him being imprisoned in the same town that his capture triggers the world state change of. You can imprison the Bone King outside of Stobe's Gamble and then bring him to the Keeper for your bounty after the world state has overridden the town.

But aside from the Bone King suddenly being out and walking around when he shouldn't be it doesn't negatively impact anything else. The hostile bonemen will despawn and the Graveyard Keeper will take back control of his home.
