## Description

When the craftassist agent sends a /point chat to the minecraft client, the area that is pointed is not the same size as the bounding box that is passed in.

## Current Behavior

Flashing voxel area is smaller than the object being pointed at (and the coordinates passed in in chat).

## Expected Behavior

All voxels in the bounding box should flash.

## Steps to reproduce

Use the `point_at` function in the craftassist agent and compare the expected to actual voxels flashed.
