Continuity errors

Contitnuty Errors are minor or major irks in timelines and stories. Minor errors can be ignored, but major ones can leave gaping plot holes. Sometimes, side stories can help patch things up. No one likes plot holes

Examples
Pretty much sums it from the canon page. Some people who write fictional works or make games or films try to be careful with their canon. Mistakes will always happen, though,
 * Character appearing out of no place. When they first appeared, it explains how they got there.
 * Character pasts, injuries and other stuff.
 * Location hops. How did character A get to place B so fast?
 * How did character A befirend character B when character C rescued or saved them?
