Hello, today I went to enter the new version that just came out 1.17 21w08b, and I found some bugs involving water and the appearance of normal ores among Tuff, I don't know if the problem can be Tuff, for the reason that I found some correct in layer y: -45 between Tuff. I know that you are doing everything to improve these wrong generations, but these are bugs that we want you to fix quickly! Thank you have a great day !!!
