Objects not converted when saving back from AC22 to AC21

Hello all,

I've encountered problems when saving backwards a project from AC22 to AC21. All objects, windows and doors don't convert and are missing in AC21. All I get are the trees.
I suppose it's a bug, very annoying when I have modelled all in AC22 and have to exchange with fellows in AC21.

Not the most ideal solution, but it works.

If the object uses commands that are new in version X then, when downgrading to X-1, the objects will be "broken" - they will downgrade, but due to the content they will cause errors that finally will show a "dot".

Given that every type of door and window fails to convert, rather than fail to generate, I figured it was more the fact that they did not script in the backwards convert for many of the basic AC22 objects... I have not noticed any differences in them from AC21. I do not recall having this issue saving v19 from v21.
