+Subject: [PATCH] Prevent Pathfinding out of World Border
+
+This prevents Entities from trying to run outside of the World Border
+
+TODO: This doesn't prevent the pathfinder from using blocks outside the world border as nodes. We can fix this
+by adding code to all overrides in:
+ NodeEvaluator:
+ public abstract BlockPathTypes getBlockPathType(BlockGetter world, int x, int y, int z);
+
+to return BLOCKED if it is outside the world border.
