STrackLevelUpPath=\\vault\TES4\LevelData\
bTrackLevelUps=1
are the defaults which I have never seen before it was pointed out to me.
Like I said, this isn't about leveling up, but crashes on trying to save. I disabled Streamline since it kept trying to save despite me setting the Streamsave to 0, only wanting reminder messages to come up which never did.
I have done tests where I just stay in Chorrol, outside after loading in, come back maybe couple hours later, save>crashes.
I just did this with a macro running to train h2h with the training mod I have with the target board in the back of the fighter's guild. I did pcb before saving. I saved successfully it said, then hit ESC and it crashed. I got lucky that time saving my skill ups.
