In Backtrack 5 R3, Reaver saved sessions to /usr/local/etc/reaver. In Kali, it is saving them to wherever the calling console window was navigated to. Additionally, there was also a database file created in Backtrack 5 R3. In Kali, there does not appear to be a database file being created. The session file itself looks good; but, when I start reaver back up, it doesn't load the saved session. I also tried copying it to /usr/local/etc/reaver where Backtrack saved them; but, that didn't seem to help either.
