U3, Character controller falls through ground plane?

Anyone else seeing this with your Unity 2.6 projects once imported and run in U3?

It happened to my scene. I replaced the controller a little higher (Y-axis) and all was good. I did not investigate further though.

Ok, I found out it was my AI script that caused it. Will have to look under the hood a bit to see why the change between 2.6 U3.

Basically the simple Enemy AI from the FPS demo from way back.

Will update once I’ve figured it out.
