FINAL FANTASY XIV: A Realm Reborn Hot Fixes (Feb. 26)
The following issues have been addressed.
•The servers would crash under certain circumstances.
•The Manor Sentry does not disappear after its HP reaches zero in the last encounter of Haukke Manor (Hard).
•Character movement lags considerably and/or actions take an unusual amount of time to trigger in certain instances. (PlayStation®3 version only)
•Character movement and controls are unresponsive for a brief period after interacting with NPCs or viewing event cutscenes.
•The graphics in certain cutscenes during the quest “The Rise and Fall of Gentlemen” do not display properly.
•Characters appear to float in the air momentarily after dismounting.
•Transferring an item to a retainer will sometimes result in the icon of the transferred item remaining in the player’s inventory instead of disappearing.
•When placing an item for sale in the marketplace, the initial cursor position is on the “Cancel” button.
•When using the text command “/action(/ac” or “/petaction(/pac)”, if a target character is specified, but that target character is not present, the game will automatically select a viable target and carry out the command.
* With this current hotfix, if the specified target is not present, the error message “The target name you have selected is invalid” will display and the action will not be carried out. If a target is not specified, the action will be carried out automatically on a viable target, just as if the action had been enacted from the hotbar.
•The mouse cursor is visible when using waymarks even if "Locked to Cursor" is selected for ground targeting settings.
•A player's application to a free company will not be received when an application to a different free company is canceled prior to submission.
•The client will sometimes crash under usage of a CPU with greater than 32 cores. (Windows version only)
•Screenshots will always be saved as “High-quality PNG” even if settings are changed to be lower. (PlayStation®3 version only)
•A section of Help text does not display properly on the World select screen during character creation. (PlayStation®4 beta test version only)
