While I was loading an 18w48a world while I was looking for the New Village in a survival world. All 3 of these issues in the .txt files happened every time I tried to open the world after I teleported to the Village after the /locate New_Village command. I don't have the best computer though so my conclusion is you should make Java Edition more compatible to slow and small PCs. I can't use my world until this is fixed so please help me. Thank you!!
