Null Reference Exception when Atomic Power Bank explodes

I'm getting NullReference exceptions associated with Atomic Power banks exploding at end of life.  Have reported the crashes.

I suspect that this is happening when the power bank is moved out of a spaceship onto a planetoid between saves.  I have noticed that when I move atomic power banks out of spacecraft, the end-of-life warning does not update - the warning shows still for the spaceship, even though it has no atomic power banks on it.  

BTW, save/reload causes the warning to show for the planetoid correctly.

EDIT: I've also seen this (or similar) for a power bank that was stored in a storage bin in a spaceship and not moved out.  Maybe the whole moving thing is not relevant, the common factor as far as I can see is that the power banks were in a spaceship.
