Update 10/19/2011 Currently looking into the animation issue and I will update this as I have news.
Update 10/20/2011 Animation Issues potentially fixed! Please re-convert any objects that had failed animations and let me know.
As most people know, there has been a major upheaval in custom content with the TS3 patch that came out on Monday 10/17/2011.
The cause of the problem is that the _RIG resource has changed formats. The original used an encrypted format that required a ton of work to read and write. The new format is much better and there is already a s3pe plugin to support the format (Thanks Peter!) so it will be a much better choice going forward.
HOWEVER for the moment, all of the cc that uses _RIG resources are broken!
The attached file is a program that automatically converts from old to new format so that you can fix your own content.
It needs a ton of testing, and may make things worse for some items. So please be careful to keep a backup of any CC that you try this on.
