Changes in resource chests04.10.2016 15:34:54
The following changes in the logic of the resource chests will be implemented in all realms on 18.10.2016 at 15:00 server time:
1. The content of all chests which are equal to certain hourly income is going to be calculated at the moment of their receiving and won't change dynamically as the income changes.
2. When a realm is restarted the chests will be transferred to the new era with the
minimum amount of resource according to their hourly income. The minimum amounts can be seen in the info screen of the Hoard.
NB! All chests received before the time of the change will continue to be calculated dynamically until they are used.
