Alien Research (TFTD)

Information recovered from research of alien Medics may break the research tree progression. Don't research live alien Medics until the very end of the game, because you may need to interogate the actual live Alien (or research its corpse) instead of getting the information second-hand from a Medic class Alien.

One user reported (but is unable to confirm) having problems getting the Thermic Lance and Vibro Blade if they didn't have the Calcinite corpse to research. If the information was obtained from a Medic, then they would never get the option to research hand-to-hand weapons

Has anyone else found this problem, or can they elaborate on this? - Phoenix
