[XLand] Between a ramp and a wall, it seems like the structured grid is not being rendered.

The bug can be reproduced with any of the scripts of XLand. You can see that in the following image, on the side of some ramps, instead of gray terrain, there is just white (which is simply the background color).


The issue is probably on the grid generation in ProcgenGrid, and more specifically in the generation of the actual map (generate_map function in simenv/src/simenv/assets/procgen/wfc/build_map.py).
