Is there any way to disable victory conditions within a savegame file? I just won a technological victory after having researched (or stolen) every single tree, and it felt especially anticlimactic, especially considering that pretty much all the races left me completely alone and I didn't have a single conflict of any sort. I have a savegame from about 3 turns before the victory, and I wanted to use it to try to win through conquest, but obviously I can't, since I'm forced to a tech victory after 3 turns.

Anyway, any help would be most appreciated.
