sorry, I'm posting this from a Mobil device, so this might be a little screwy.

my girlfriend brought her hard drive over so that she could play her character while I was at work. I've got dawn guard and hearth fire installed, she's only got hearth fire.
ive got them both installed on my hard dive, not the system. but when she got home and plugged in her hard drive to her system, it gave a Content Not Available massage for every save she made at my place, and when she loaded the saves her hearth fire home was missing, and several discovered locations weren't on the map anymore.
any ideas?
