I recently built my whole town (house, cow/sheep/chicken/pig farm, Workshop, Garden, Enchanting room, Whole underground mine, Nether portal) i went into the nether and spent about a hour there, once i come back out im way away from my town (on cordinates) and i have a enderman and magma follow me out that kills me. once i respawn back in my house i come out and literally half the place is gone now???
