When playing game, if you are traveling, building, mining, and especially fighting, game freezes/hesitates during autisave.

When mining, blocks will disappear, then after autosave completes, all the broken blocks update and then item drops.

While fighting, you hit enemy 3, 4, or 5 times, like a zombie, with a diamond sword with Smite V on it (should be 1 hit one kill on zombie with no armor). Mobs will not die until autosave completes.

When traveling, like in minecart or horse at high rate of speed, when autosave hits, you freeze in place intermittently. 2-3 times while autosave completes.

This is all immersion breaking and is a big pain when exploring the world at night or traveling minecart across world..
