(reposted this because i accidentally unshared it) what you're seeing is the very last section of roads in my minecraft world to receive quartz stairs as hills. for years i've used the quartz stairs as a slope if my roads in my minecraft world come into contact with a hill or if it's approaching a bridge. but now with these brand new wool stairs that just dropped as an experimental feature for the next big update of this year, the whole world is going to change. now the hills will look more accurate and not use quartz stairs as hills. here's an image of the last ever section that received quartz stairs as hills in my world before and after the wool stairs were added in (good luck to myself for replacing all the quartz stairs with wool stairs because there's like thousands of hills in my world and it'll take like months to finish lol)
