Unhappy RestrictedAccessException: Group: only a BranchGroup node may be removed - 06-23-2011, 07:02 PM

Hello,
I'm having a problem when leaving the current working world. Because I (obviously) didn't write Alice, I'm having trouble locating where the problems are and how I should go about mending them. I attached the error anyways. Thanks in advance

That's a new one for me. Looks like something important has been deleted from the world, though I have no idea what.

This is one of those errors that can't really be "mended" per se, since no one really understands what it means (except maybe Dennis, but he's crazy busy). I'd recommend restoring your backups and working from those. If the error persists, try to identify what you did both times that triggered it so we have more to work with.
