It appears that a repeat of the event has not concluded identically on a similar situation, this time I was researching UFO Theory as opposed to a particular craft and my scientists were returned to base with a grammatically incorrect message pertaining to the subject. 'Prerequisites met not, research halted', (I had a look for the text output .cpp to patch grammar but could not find it someone passing may spot it).
I had already submitted this as a bug ticket, but it is appearing further to be a 1-off bug.
