Group notices that are received before any group chat window for that group has been opened get logged into "group_name.txt" instead of "Group Name (group).txt". Once you open the chat session they are logged into the correct file together with the group chat.
Possible reproduction steps:
  1. Receive a notice (either on login or later)
  2. Open the group chat
  3. Receive another notice
Both notices are logged into different files.
