Bug Description

I'm using arnis to generate a map of the campus, and for further edit and decorate, I changed the scale to 2 so that there're more place for us.

However, when using the scale 2, I found that while the map's size do changed, the buildings' height for each level is not(they're still 3 blocks high each level, but I expected it to changed to 6 blocks, since the scale changed), and some of the higher buildings even have the top level cut into half.

When I'm using the normal scale, it generated just fine. Although plenty of decorations on ground are missing(I don't know whether they existed on the OpenStreetMap, and the map online is kinda old), the scale is right and it's usable, so I think it's not caused by missing map data.
Also, when I tired the scale 0.5, just to prove that I didn't got the scale wrong, it seems that the buildings' height per level still remains 3, and also got some of the poor top level cut in half.

Screenshots

The screenshot of a poor building with the top level cut into half in the scale 2 world:

As you see, the height of each level is still 3 blocks high...

The screenshot of another poor building with top level cut into half in the scale 0.5 world:

I didn't expect this to also work though, I do understand that changing a map to a smaller size in minecraft will cause problems.

Additional context

Also, I had trouble on loading the world generated by arnis, the minecraft complained for chunk data not found and even refused to load my skin(just keep complaining), so I used a map generated normally using the same minecraft I used to load the world. I don't whether that count, the campus still generated on y level -62 though, so I think that's not the cause.

Need to mention that I'm using the command line to generate because the program just freezed when I tried to load an existed world in gui, but I think that's a problem of tauri...
