It should work as long as you are using the most recent version of Placeable Design Kit
I appreciate the feedback! I just retested everything on my end, and it’s working as expected, so unfortunately there’s not much I can change on my end. One thing to double-check is that you're using the most recent version of the Design Kit mod. I ran into a similar issue myself — when I updated, it didn’t overwrite the old version because ThundR changed the name of it, so I ended up with both in my mods folder. I was using the outdated version for a while without realizing it, and it still worked for most other buildings. But eventually I started having issues and once I switched to the newest version, the issues were resolved
