World Freezes

In a online multiplayer world with another person, I was about 3 thousand blocks away from my spawn and I broke the middle piece of a three block height of a sugarcane. I expected to gain two pieces of sugarcane. However, instead autosave turned on and the world froze, yet time was moving as normal. Both me and the additionally player left. I couldn't save and quit I had to close the game from the PlayStation game menu screen. Then when we joined back half the world was unloaded and the game was still frozen. The second player was floating and everything was still frozen eventually I could move and place blocks. However, the blocks were invisible/disappeared. We duplicated the world and tried rejoin it did the same thing. Happily we gave it a 40 minute break and the duplicate is working. This type of issue of placing/destroying a block and autosave crashing the world has happened many times before. However none was as severe as this one. Normally rejoining works, but this time it didn't until way later.
