Lately I've noticed that in my years-long creative world, in 1.19.80.21, it takes much longer to load the world than it did in the previous build. When the world finally does load, it lags tremendously for approximately 20 seconds before going back to normal. Then, when saving and exiting the world, the game lags in the same fashion and crashes.
