"After completing the Liberation missions you'll need to find Deborah "Dobby" Carter. Some have reported there's a bug that her Liberation Mission icon disappears. She's located in the Northwest area of New York North District almost on the corner of the furthest northwestern road. "
I am going to try that map and see if she appears when i get there.. it doesn't even list talk to contact on the rationing mission so.. if she isn't there I am screwed and cannot collect my last assassin... ac3 has SO MANY BUGS.. I thought the first one was bad.. ugh..
