I would contact the owner and do the shoot again. I would take a spare battery, use my phone and ensure the location is well-lit if I couldn't borrow a camera. I would save backups after every shoot to an USB drive to avoid losing images if the camera's memory was wiped. I would use alternative software and fonts or a different computer to complete my magazine if my preferred options weren't available. Having backup plans addresses possible issues that could come up and helps ensure tasks are completed efficiently.
