defect happened in corner mesh when mesh id=28

Hi , I checked out the repo and tried to generate the randomized block building

We can find out the defect happened in mesh id=28 when the grid elements filled likes this way in the screenshot.

Just want to confirm it's a assets bug instead the logic error. Thanks for your amazing project !

Finally I figured it out ! If I changed mesh 28 to be like mesh 44 with symmetric part of bottom, it works !
