T7- I'm sorry it's caused so many of your savegames to get corrupted!
Okay, so I'm reading that there's a problem giving NPCs a Jedi class. I'll start with that one.
When you add a Jedi class, you immediately see a Force Powers leaf appear underneath it. You should be able to click it and see selectable force powers on the right.
The KSE.log will be written to only if it exists. So you have to create it.
