When you are typing to someone during a PM, and they /nick to another nick, the logs continue to log as the previous nick instead of making a new log file.
Reproduce:
Simple. Just either make a clone of yourself or ask someone to message you. Then type whatever and have the other person or clone type back. Then just have the clone/person type in the PM. Then go to the log directories and you will see that there is no new log for the /nick, but if you open the log of the old nick you will see the conversation there.
