Minecraft 1.17 is right here and, in fact, there are bugs to fix. Ore distribution obtained knocked around a bit with the launch of 1.17 - though the builders stress it hasn’t been as bad as you’ve thought - and a new pre-launch update takes goal at these issues. Assuming no main points are found in this second pre-launch patch, you need to count on to see the fixes land in 1.17.1 quickly.
For the reason that launch of 1.17, diamond ore has been generating one block off of where it ought to have been in Java Version. That’s getting fastened in Java 1.17.1. szv7 is separate from the Bedrock bug that made diamond ore much rarer, and even that drawback has already been addressed as of Bedrock Version 1.17.2.
This update also fixes a bug with emerald ore era in Java. Since 1.17, you’d get between six and 24 emerald ore per chunk - the meant amount is three to eight, and the ore is back to normal with this patch.
