I'm not sure if this is a bug. It's at the very least a concerning issue. I created my world in 1.16.5, before 1.17 was released. I've tried finding amethyst geodes in both new chunks and old. None appear where they should be in my world. When I've loaded up the same seed in a new world, and have gone to the coordinates (according to chunkbase . com) the geodes are in their proper location. My world seed: 7882252406223859695 Am I doing something wrong? Is it possible for me to import my world into a new 1.17/same seed without losing everything?
Previously explored chunks can't get new geodes in
I would suggest that geodes are sparser than you expected.
You will find geodes by just more searching, but if loads of chunks were generated, you may need to go a bit farther
Or you could look in spectator mode if you like
