Problem 1 (Solved)
While I was walking in my village to give breads to my villagers I heard a strange noise. I stopped and then I began to hear other scary noises and that made me frightened. (According to this, I reported the same noises and responded that it came from the blocks of Blackstone(blackstone bricks, stairs, slabs and more) but my village was built from houses of villagers created by the game and I'm not using blackstone. I also saw that the villagers began to flee when I heard the noises) Please help us.

Problem 2 (Not resolved)
(You might be able to help me. Moving my village from the flat world to infinite world or change the world that form flat to Infinite (and make the village will be in the new ground level with all of the villagers and iron golems)
