Bug Description

Hello,

I used blenderBim since years in a Blender Plugin, which worked great.

For a long time, I hadn’t seen any need to switch to Bonsai.
But since I wanted to add some new features, I decided to look into it today.
In the process, I noticed that with Bonsai, some walls are simply missing or are no longer displayed.
I can’t recall exactly which version of Bonsai this started happening in.

The IFC files we work with come from an external service provider, https://www.archilogic.com/, and unfortunately, there’s nothing we can do about that.

thanks, greetz Stefan
