Which World events/ World quests will be affected and might fail if the server is reset to the previous day state?

Question

For which events the reset of the server might cause fail in the event and how the situations like that are usually dealt with? Are the events extended?

Answer 1

It should not affect the state of event, as it takes server state back to previous day, including event progress, so it cannot be failed just by reset. If it comes to extending events, it depends on Cipsoft decision in specific situation I think. But it happened few times that they extended some events, so it is possible.
