After a Battery was destroyed by a meteor shower, the battery extensions remain in the world as 'ghost' objects. They don't have collision boxes (you can walk through them), they can not be disassembled, it is even possible to build new battery extensions for a newly build battery at the same position. However, the latter one leads to uggly graphical glitches as the models of the destroeyed extensions still remain in place. (If there will be a screenshot attached, you can see it, if not that would be a feature request for Feedback to make it possible to select if savegame or screenshots may be attached).
