My singleplayer world I have been playing since the start of 1.14 keeps crashing my game when I log into it. I just played this world last night and didn't have an issue, I properly saved and everything, I am not sure what is wrong? Recently the world was converted into a realm, and then back into a singleplayer world so I'm not sure if that had anything to do with it. Any help would be appreciated I have had this world for almost a year so its like my baby, haha.
Here is the error: The game crashed whilst exception generating new chunk
Error: java.lang.NullPointerException: Exception generating new chunk
