This thing generated less than 20 blocks from world spawn and made a giant hole in the terrain.

Only mods I have modifying worldgen are BWG, Ksyxis, Sparse Structures (forge port) and Noisium.

Don't know if it's crazy rng or just sparse structures shenanigans, but wow these are everywhere at spawn

btw the initial subject of this issue is the giant hole in the terrarian caused by the structure, I just happened to notice that they're suspiciously common as well.
