I'm having a repeated crash when I go to add a new AI Package and click the IDLES>Use Specific Idles>Add new, and try to choose an actor to demonstrate the idle. It happens every time, crashing the CK, even though I make sure not to touch anything after hitting my selection. Has anyone had any luck with this feature?

I can't get into it either. I tried a couple of different ways. In my own plugin and in the Skyrim.esm and in a new package and in an existing one. Crashed out every time. I'm pretty sad about it. I use this a lot.
