I have upgraded to the current build, and used old save games, so these may not be relevant at this time, but I thought they were were checking into.
1) I have not made it far enough in the game to research the XVI stuff. But the button shows up on the geoscape and it occasionally works.
2) Also, I only have one alien containment at a base, before I upgraded I was able to xfer aliens after a mission to whichever base had it. That pop up is not happening. I am not sure if this is a bug, or the aliens just died after stunning them. I went on a mission in Egypt, a solar array one. Cool map BTW. I stunned about 5 aliens but only 3 showed up as captured. There were no grenades or firing that I saw that could have killed them..just something to watch for.
