Same issues, Im trying to bring it down to a particular option, but I cant. I know NOT using the trainer fixes this, but alas, there we are.
I will try not to use option 9 4 or 6. See if that works.
The last crash I had, I wasn't using option 9.
I think I was using 1 4 5 6 7 and 8.
Alas it is bedtime. After the last crash when I reloaded my gave, all my shepard stats had reset again. This might be a situation here maxing out my level might fix the problem. The game may be periodically checking that I don't have more stat points than I should have. My squad mates seem fine.
