This is shown on the Tech tree screen when the game is paused and research is changed from one which "is too advanced for our lab" to one which is not too advanced. (It's shown before switching too, but it's correct then.)
Image 1: Current research is too advanced for our lab -- No Lab Available (correct). Game has been paused.
Image 2: Research has been switched, but the "No Lab Available" warning is still shown (incorrect).
Image 3: Game has been unpaused, and the incorrect warning has disappeared.
