i leave the game, later i return to it and open the tech tree to find that the tech "Rocket Travel" is selected in the top right even though you can't see it in the tech tree.
The icon shows a rocket lifting off but there are no other details (science pack requirements, etc).
Not sure what the dev is planning to do with this but it looks interesting.

( i did this in .10 not sure if you can see it in the other versions)
