When does the tech tree load? How can I try alternative Tech Trees?

[Wolf Baginski]

There are several alternative tech trees out there.

I have been assuming that an alternative tech tree loads with all the other Mods, applying to all the different games that can be selected. such as Science and Career and their saved games.

It strikes me as possible that the tech tree could be loaded when a saved game is restored. Since the save stores the unlocked nodes there seems to be some potential for awkwardness if it doesn't happen this way.

I am thinking of trying a different tech tree, one which better handles some of the large-size tanks and engines, and i wonder if I need to set up a second copy of KSP just to use a different tech tree without breaking anything. That looks to be the only safe option.

New Tech Tree = New save. I had this problem when I installed KSP Interstellar. What I did was add up all the science I had earned (unlocked nodes + whatever you have left) and write down my funds and reputation. Started a new savegame and transferred everything through a mix of savefile editing and hyperedit. Worked quite well, although it was a hell of a lot of work

Edit: Oh, and to answer your question, the tech tree loads once, when you create a savefile. At least it used to, someone correct me if I am wrong.
