Pulling the plug on the BattOr can kill the program stored in onboard flash

The BattOr was running and I pulled the 3-pin plug and put it back in and the BattOr came back online and was stuck in an infinite loop in the bootloader.

This could be because the voltage watchdog on the Atmel chip is not set properly in the fuses so we are running it at too low voltage during the unplug transition. It also could be because we are not protecting the onboard flash memory addresses so they can be overwritten by the program itself. Maybe we can set a fuse to prevent this too.
