Hit locations and missing locations

[Steve]

If a character is struck and the hit location is rolled for, what happens if the rolled hit location is missing or desolid? Does the attack miss completely, the GM changes the location or is the location re-rolled?

 

Example: Character A is in a fight but their left arm is desolid or missing. The left hand is what comes up after rolling for location. Does the attack miss completely, is it shifted to the right hand instead, or is the side not even rolled for and a hand location automatically becomes the right hand?

I'll leave that one in the capable hands of the wise and insightful GM.   Personally, I'd probably have the attack miss, but other GMs may look at the issue differently.
