Gonna plug my own project here. I made a mod that lets you easily start a new playthrough of SO with different choices. You just select any of SO's main events as a start point, and the mod will prompt you to make any choices you would have encountered along the way. So, you could use it to quickly try different combinations of choices and see which one caused you to miss those Tora events. You can grab it here if you're interested:
