Really kind of moot, if you experience crashes on SS then I bet you experience crashes with vanilla and/or other sub mods too. SS is even more stable than vanilla.
It could be a pain in the rear, but in the rare case of one loosing something because of a crash you could load the last game and autowin the battles you did win before the crash. It's just my opinion.
Regarding the difficulty, I think this simply make the battles a higher bet, forcing you to think more, I. E. have more depth and fun. One can still play on lower difficulties, SS it's pretty hard as it is.
