A quest needs an item the player sold, lost or threw away, and the story can't go on

Open worlds let people do anything, including getting rid of the one thing a quest needs next. Here is a check that runs on loading, looks only at what the current step needs, and puts a replacement where the player can fetch it.

Why this works

A quest only breaks at the step the player is on, so that is the only place worth checking. Asking whether the next thing needed is held or still reachable finds real dead ends without raising false alarms about things the player used up on purpose.

When not to use it

Do not use it as a cure-all. It fixes only a missing item, not a locked door, a dead helper or a story that cannot continue for other reasons. In a game that wants lasting consequences, a lost item may be the intended price; then offer a hint instead of a free copy.
