Fast Travel should be enabled by default. When you load a save, even if you had it disabled when you last saved, it should still become enabled. So I don't know how your brother accomplished that.

Anyway, the only settings are 1 and 0. I don't remember which is default but if 1 doesn't work, try 0, and if 0 doesn't work, try 1.

I do not know either how he oversaved my file before entering No gods, No Masters. The only save i had left was a quick save inside the last mission. So i enabled the fast travel by command, and now the fast travel is off in the game.
It's turns on just for one time when i hit the "enablefasttravel 1", even if i use command "save game" (saves a game named game) direct after and QQQ and restart the fast travel is still disabled :/

How about use the resetquest command on No Gods, No Masters but then i need the Base Id, that i do not have.

In someway it must be possible to re-enable the fast travel if you have "wrapped" out from the last mission.

Wait wait wait... you haven't been using an equal sign? If so, that explains a lot. You are literally enabling it 1 time. If you type "enablefasttravel= 1," then it should stay set to that until you quit the game.

Yes it could be possible that I just enabled it once, i will bring up the game and test now...

EDIT:

Didn't work, it gave me script error.
