I don't think I know what's going on with your animation there, jj :( Sowwy
I tried tinkering with cararra a little to see if I can duplicate what may be going on, and no luck.
Only other thing I may want to look at more closely (if I were you) is to see if there's something specific going on in that frame that may cause cararra to halt. However, I'm not sure what that would be...
I'm not being of much help here. I did feel like I needed to say, I'm not ignoring you :)
