so i get that red sand is hard to get and you might think this bug is good. believe me, when you shear a deadbush and you fall into a ravine and die 10000 blocks away from home, it wont be so fun. either way, if you dont know, heres how minecrafts underground is generated: stone first, ore/other material like dirt 2nd, caves 3rd, bedrock 4th and structures 5th. idk why i included that, but the point is that while caves/ ravines/ whatever is added, redsand isnt removed, therefore resulting in easy deaths. also, the glitch isnt that it can float, otherwise the particle wouldnt exist, because it woould then be considered a useless particle.
