We have just deployed the completely reworked Fleet Management feature to all game worlds. To learn more about what has changes as part of this overhaul, check out this entry in our development logbook: Fleet Management Rework
Since this entry has been posted we have also added an inline display of the current maintenance ratio which has been requested by a lot of players recently. Please let us know how you like the new interface and whether you have come across any issues.
Note: Make sure to refresh you browser once in case the interface looks messed up.
