Quote:The hard limit where chunks get overwritten is at X/Z of ±34,359,738,368, which is about 25% of the distance from the Earth to the Sun. At X/Z of ±2,147,483,648, (1/16th of the former distance), item positions, mob pathfinding and other things using 32-bit integers will overflow and act weird, usually resulting in Minecraft crashing.
