ok. I had been trying to discover Amethyst Geodes in an excitement.

it took me 3 days until just now I realized there are no Amethyst Geodes generated in my realm

I have every updated features including goats, dripstone, glow berries, etc 

 But no Amethyst Geodes !!!!!!!!!!!!!!!!!!

I personally hate using cheats, but I had to use it after 3 days of no discovery,

I changed to spectator, and there is none.

so I created a new world in my realm server, and there are Amethyst Geodes as you see in the second screenshot.

But my first realm world, where I had been playing with my friend for 3 months, has no Amethyst Geodes.

What should I do now? is there any way to force-insert Geodes in my current realm?

I don't want to switch to the new world, we spent most of our time in this world and built a lot of stuffs, memories.
