So i was in my minecraft world on singleplayer and hunted for different types of flowers far away and i then died,then when i respawned (this only effected a chunk of grass) the grass blocks and grass colour was different,one row of purple grass,one row of black grass and a row of magenta grass,and the textures on the side of the grass were wrong,some had normal textures on the sides while others had snow or swamp grass textures on the side,didn't affect gameplay that much though but i thought i may aswell report this bug and this resets after exiting and rejoining the world
