My world ive had for about 2k ingame days suddenly had massive crash issues. Noticed an area where a massive amount of chunks are now missing, in very random spots. Even took out my own player based blocks in the affected areas. Made into a realm before i noticed but chunks were missing prior. Also wont allow me to load an older save i have as backup. Game crashes, ive submitted many bug reports through psn, username Derrickslicer. World is survival only, no cheats or experimental features. Thank you for your time.
