/locate Monument freezes game and prevents reloading

Intermittent, (3 out of 5 tries). After entering /locate Monument in a new world, game froze after showing monument coordinates. Attempting to reload saved game resulted in loader freezing at "Preparing Spawn Area 27%" Happened in the first two new worlds I tried. Game did not freeze in the third and fourth new worlds I tried. Happened again in the fifth new world that I tried. (Survival mode, cheats on)
