Well this was always going to be the case unless it autosaves after every dice roll. Why does it bother people that some people choose to re-load to get the desired result on a single player playthough? That's on them and is hardly non-linear RPG gameplay either.

I am sure you will be able to download a mod on day one of release to make all your "I wanna I wanna" dreams come true and remove all random elements the dice roll system brings. Oh and DOS isn't D&D.
