So. i just started a new world and i was confused cuz there was mountains with a clean cut across it ( like a missing chunk ). i started walking then like 100blocks later, i quit the game cuz the leafs on the jungle trees weren't the right color ( like when u take a leaf and put it into a different biome). then right as i quit, i saw a crafting table!!!!!!!!!!!! in a fresh game!! not placed by me!!!!!!! i went back in and i was in a different part of the world but still at the same coords. i wrote down the seed and started a new game with it but it was waaaaaayyy different. i guess this will remain a mystery till anyone else finds one. i wonder what else was around it O_O
