Well this happened to my cousin and he figured out that it was CORRUPTED. This could happen from T-shock and other Mods. Later he figured out that in T-shock it said that if you dont exit it the right way your world may be Corrupted. READ EVERYTHING. and if this was not your case then know that this happens from other things too. P.S. My cousin looked on the map veiwer and his world was UPSIDE DOWN :P
