I was playing in my DST world on ps4 when suddenly bishop head piece disappeared, I tried to roll back as much I could with no result. At the end I just gave up and delete my world to start a new one, but the problem was not solved this time there was no bishop sculpture and no bishop head piece. I tried 3 different new world but had the same problem. Basically I lost a 160+ day world and many hours with new world tries, I can not even start a new world and that is annoying. If anyone knows what to do please let me know.
