Air Generation at Corners of Circular Arena in Trial Chambers

In the trial chambers, the circular combat room is intended to have structure voids at its four corners to prevent interference with surrounding stone or deepslate blocks. However, upon generation, these corners are incorrectly filled with air blocks instead of structure voids. This disrupts the intended environment and may affect gameplay or aesthetics.

How to Reproduce:

1. Locate a trial chamber in the world.

2. Navigate to the circular combat room.

3. Observe the four corners of the room where it meets the outer walls.

Observed Result:
The corners of the circular combat room are filled with air blocks, exposing the surrounding terrain or creating unintended gaps.

Expected Result:
The corners should be structure voids, seamlessly blending with the surrounding blocks (stone or deepslate) without generating air.
