Exposed mineshaft tried to generate in the desert near the badlands biome, generating the outline and a few rails. It isn't connected to any of the actual badlands mineshafts, nor has a coninuation below

What I expected to happen was...:
Exposed mineshaft should've generated inside badlands or not generated at all

What actually happened was...:
Exposed mineshaft generated in the desert
