Broken arm bone out of whack.

Wuggletoes

Whilst working on something, either I fat-fingered something, or something went wrong undoing a script, but now my model's arm is busted... in the save file even!

Using a zero preset makes her look normal for a bit, but then, move it a bit, and wham. Turning on the bones display, it seems it's dislocated, but I'm unsure how to reattach it...

Oh, just got it. Posting it for any future reference:  Gotta restore the rigging on the selected node (selecting it via the Joint Editor). Voila!

 

Now to figure out how the frak I messed it up in the first place!
