GOT IT!! The problem IS with the latest CBA version (including the hotfix). Without that, it all works fine. So it isn't Eden, it is CBA. Now whether these changes are something ALiVE will have to adapt to or whether CBA will straighten out, I don't know. But for now, reverting to CBA version 2.2 seems to make things happy again (easily done using WithSix).
And there's 8 hours I'll never get back...
