Okay, I can see there are quite a few people with chat tabs disappearing. I have yet to see this phenomen, although because so many are reporting it there must be something happening somewhere that is common to all of these people.
1. Are you all using Prat or Chatter ? - I am not using either anymore
2. Are you using my nUI_InfoPanel_.... Chat Frames ? - I have them always running
3. Are people able to give us screenshots of the chatframes existing without nUI and not existing with nUI ? - Here's my screenshot with nUI active ( 5 and 6 ) with all the chat tabs existing that have existed for a long while now.
chat-cache.txt pertinent information ( removed messages tracked for space reasons ) for the character in question. And, despite seeing this for the umteenth time, I have finally realised why my chatframe plugins don't always show the right messages per frame ( I'm not storing chosen chat frame ID per character *slaps head* ).

Anyway as you can see I have quite a few frames stored in file and these are all displayed in game as expected. Docked = postion after ChatFrame1, Shown = visible on screen.
