So basically I have this Minecraft world called Minecraft city, Where people basically just build there own house, So very recently the world would randomly not respond to anything, Type in chat, Nothing, go in a chest, Nothing, Anything you would do nothing would happen, If you placed blocks after this weird bug fixes, Every block you just place gets deleted, I have a couple of command blocks in my world in a ticking area but that's it, This only happens when I am far from spawn or there are multiple people, Lowering my chunks also seem to work, When it's only at 8 chunks, Please help!
