????

ok so i have been playing minecraft and i have been seeing wierd things.
like villagers chatting through walls, strange torches on my singleplayer survival world.
and once i went mining afer making a house and when i came back up my house was blown up.
i had no tnt so anyone know who or what is was? my chest was gone and my crafting table.
now something. i was playing on a server and it kicked me for hacking when everyone was alllowed to change between survival and creative.
