I am having an issue where in the world, all game mentioned structures are now spawning at an extremely low rate. especially the three mentioned in the title. Has anyone else had this problem?

Not sure how we'd be capable of doing that as we dont ever touch structures

Closing this as we're 98% sure that we arent at fault here

I have confirmed that it's not a fault, it's more of just there are not as many structures in the BYG biomes as there are in default biomes. And shipwrecks were only because the seed didn't have very large oceans. Thank you.
