I'm generally only in favour of a rollback if something absolutely crucial occurred you could make preparations to prevent which would cause severe problems for your strategic position. (e.g. a major fort was being stormed and you needed to prepare the orders for its defence.) It also has to be something so critical that it overwhelms the importance of everything else that went on - for instance, if two other nations had a huge battle, a rollback allows the loser to change tactics or avoid the fight.

I appreciate it's annoying to lose a turn by corruption - I've suffered it and probably anyone who has played plenty of games has - but unless it makes a vast, vast difference to your position, it shouldn't really be done.
