Yesterday's Enterprise Episode question
In that episode we see that Enterprise D changes when Enterprise C emerges from the anomaly, Worf is no longer a character and Tasha is back because they never visited the planet where she was killed ( "Skin of Evil" Season 1, Episode 23). My question is wouldn't data have disappeared as well? He would have never been discovered because the federation and Klingon have been in war for many decades.
