Client fixes and updates

A client update is available for Main and Test. Install it through the Launcher to get fixes to Helper, the interface and graphics.

• Updated materials for Castle Siege, Blood Castle, Arena, Devil Square, Chaos Castle, Land of Trials and Barracks, as well as many monsters, NPCs and some equipment. Model sizes, geometry and game effects have been preserved.
• Reduced unnecessary memory and rendering work. Removed screen layers of sand and fog on Tarkan and several other maps; some persistent effects now update at the game logic rate rather than every frame.
• Helper filters item names and numbers more precisely, adds Symbols of the matching level to an incomplete stack even when the inventory is full, and automatically repairs eligible equipment when low durability is reported. Settings now have an exact delay in seconds, clearer buttons and a reset to defaults.
• Fixed a case where Helper repeatedly tried a failed pickup and stopped attacking.
• Fixed automatic buffs during attacks and BK combos in Helper.
• Fixed DL Earthshake, both manually and through Helper, when Dark Horse is used from the inventory.
• Ctrl+number shortcuts persist after logging in again. Party invitations support Enter and Escape; Personal Shop price confirmation and cancellation have been fixed.
• Updated labels for Zen operations and the Storage/Warehouse switches. Fixed repair button positions on Full HD and maximum durability display with the limit of 255.
• Fixed a case where the client ignored a server position correction. Fixed cleanup of repeatedly removed objects and closing the Chaos Castle window when a ticket is unavailable. The reconnect window shows connection and diagnostic status.
• Spanish and Portuguese movement tables now match the selected server.

Client updates do not transfer Test balance or server mechanics to Main.
