Save Error: java.lang.NullPointerException with 4+1 Mezzanine House Project

[kadirumit]

Hi everyone,

I've been working on a 4+1 detached house with a mezzanine floor, based on one of the demo houses. However, whenever I try to save my project, I encounter the java.lang.NullPointerException error shown in the attached screenshot.

I suspect this issue might be caused by specific objects or assets within the project. I am currently using Sweet Home 3D version 7.6.

To resolve this, I tried creating a new project and copying all the contents over, but the issue persists, and I still cannot save the file.

Does anyone know how I can fix this error without losing my multi-story design? Any help would be greatly appreciated.

Best regards,

To get more details about this error, run Sweet Home 3D from the command line with a command like:

Code: Select all

"C:\Program files\Sweet Home 3D\SweetHome3D.exe" 2>log.txt

and post here the text of [font=courier new]log.txt[/font] when you try to save.
