The game is crashing

I was cruising on a boat and got kick out of the game. I tried to restart the game several time, but it keep crashing without having the time to do anything. The last time (try #6), it gave me a message.

The game crashed whilst exception generating new chunk
Error: java.util.concurrent.CompletionException: java.lang.RuntimeException: We are asking a region for a chunk out of bound | 29 -29
