As mentioned I‘m unable to research the „Live organic alien“ technology!
But until I post this as a bug, I want to make sure I didn’t miss something important.
I‘ve already researched the „Alien breathing apparatus“ technology and captured a living organic alien (Taman) on the battlefield.
The Alien is displayed at the alien containment-screen and it‘s also visible on the main-screen of that base.
Additionally there was no massage which acknowledged me about new research options.
As an additional slightly confusing fact, there are two types of Taman-corpses stored in my containment-facility (At least they are occupying two different slots of my containment-facility).
My current version of UFO AI is „2.5 Win32 Dec 9“, but my campaign was originally started in "UFO AI 2.5 Win32 Nov 24".
A corresponding savegame is attached.
Thanks in advance for responses
