Top wall don't collapse??

I’m working on a wall mod. And have made some new models. And used the wood wall files in the editor to make them out from, changing models etc.

But if I build 2 walls on top of each-other and delete the lowest, the top one doesn’t collapse and just flote in the air??
What settings is used to prevent this? And I don’t get way it does it as I made it from the wooden walls??

Hope someone can help :slight_smile:

Just a lucky shot. Do you maybe changed the walls to not need any support or foundation?

Yah it can be build anywere :slight_smile: But i still would like it so that if you build it ontop of eachother and delete the lowest the others fall.
