Take a look at this unofficial .beam update on my Google Drive
You will need to replace it manually into the C:\Program Files (x86)\wings3d_1.5.2\lib\wings-1.5.2\ebin folder (or a name like that).
After that, you should see an new "Save" button near to OK/Cancel. It will save only the Wings3d default material properties (not the plugins ones).
In order to enable the Diffuse color field can be changed you need to change Vertex Color to Ignore. It's already this way - just in case you don't know about it.
Play with it and tell me if it's ok. here, at least it didn't break wings.
I'm still playing with it and it can still be changed.
Important! Don't forget to backup the old file before replace it.
