How do you upgrade a saved game

I’m in the process of trying to fix the TTA bug. I’ve fixed the bug but am stuck on creating the 2p and 3p saved games. I tried upgrading the existing ones, but that didn’t work (taking the start player card didn’t seed the current event deck as it should have).

So now we’re trying to manually rebuild the saved game as you suggest, but the problem is I don’t know how to create the 2p saved game to begin with. I tried starting with a 4p game (which doesn’t load a save file) but that resulted in a saved game file with players = 4 which is not what I want. I was hoping that setting it as the file to load in the 2p predefined setup would reset the value of players to 2 when the user selected a 2 player game, but it stays as 4.

HELP!
