Thankyou for playing and letting me know about this bug, I'll definitely take a look into how I can fix this and create an updated version.
I had that same bug, too. Wasn't even sure if it was a bug, but then the journal entry for the battery changed position. I was able to pick up another battery (even though it was no longer on the ground), and then disappeared when I walked between two buildings! Like, the camera just didn't move and I couldn't see her to get her lined up to come back out.
