Quasqueton said:DM's: Have you ever sacrificed cause and effect to prevent the derailment of a game?
Yeah, but not in the way you mean (I don't think). I rewound time once to prevent a TPK: oh, you turned off the tap in room #113! There is no poison in this room, so... let's just start the encounter from the beginning.
The example that you give about the dwarf fighter derailing the adventure - I don't think he did at all. Why not come up with adventure relating to the town guard, breaking out of town, etc. Put your planned notes off to the side and run off the cuff for a while.
(That while is as long as the players are having fun.)
