Bugs fixed in 21w18a

Hey-hoo! Will you look at that! It's Wednesday once again, which means we get to share updates about all the Minecraft bits and bobs. This week, we're distributing an ore distribution Snapshot for all you lovely Snapshot connoisseurs to feast upon. Enjoy!

Changes in 21w18a

  • Infested Blocks are no longer instantly destroyed, and instead have half the destroy time of their non-infested counterpart.
  • Screaming goats will use their ram attack more often than other goats will

Minecraft Snapshot 21w18a Ore Distribution Ore distribution in snapshot 21w18a. Click here for a link to the full resolution image.

  • Reduced copper spawning a bit, to compensate for large ore veins
  • Large ore veins are slightly more rare and slightly smaller on average. But the size varies a lot so you can still find huge ones.
  • Increased chance of finding raw ore blocks in ore veins
  • Cave carvers generate below y 0 in ocean biomes (they didn't before, it was an accident)
  • Increased the minimum size of noodle caves and carvers, to make them easier to traverse and less likely to break up into fragments.
  • Noodle caves no longer generate above y 30, so the surface should be less riddled with holes.
  • Removed deepslate blobs above y 0
  • Extended the vertical range of the smaller blobs of iron ore, to make it possible to find iron in caves near the surface.
  • Slightly reduced the amount of normal-sized iron blobs, to compensate for large ore veins and the increased range of smaller blobs.
