There are times when you might experience an Unexpected Error. When this happens, you should play safe and not use up any energy, arena orbs, Frontier Hunter orbs or any other resource like Metal Keys and Jewel Keys. Unexpected Errors can cause you to lose quest progress and miss out on quest rewards and the problem will only be compounded if you try to use more resources while the errors are still happening.
When you encounter an Unexpected Error, hold off using resources and check the official Brave Frontier Global Facebook page and wait for an official post stating when the issues are resolved.
While we always regret any disruption of service, there is no guarantee that any lost items or quest rewards can be restored when Unexpected Errors happen.
