I'm pretty sure there is no ancient debris in my world right now.
I've used up to 3 stacks of tnt and 50 beds in Y 16 without a single debris. I easily found some in a copy of my world but none at the same coords in the original. My world has been created before 1.16 so the copy's nether differs from the original's nether. I straight mined for one hour in Y16 in chunks that I didn't explore before the update and didn't find any debris. Help!
It only will generate in unloaded chunks that you haven't loaded yet
