0.12.3 (Windows) -- Nether Boss Weirdness

For a while I was finding no nether bosses.

Then, I was finding only nether bosses.

Now I’m finding only False Gods.

I feel like this is escalating and I don’t know where it’s going next.

Edit: Where it went next is the game crashed when it tried to load an undefined false god.

Edit 2: It stopped but I don’t know why. I think it may have been triggered when I “overwrote” a nether boss fight with meeting a god for the first time.
