During March 2025, Brynner Art focused on improving the shop interaction flow in the rathena/rathena repository by addressing a critical bug affecting Arrow Merchant and Ninja Tool Merchant shops. He resolved an issue where players could become stuck after pressing Cancel by replacing the close command with close2 and inserting break statements after callshop commands, ensuring proper shop closure and responsiveness. Working primarily with scripting and bug fixing in the context of game development, Brynner applied targeted regression checks and code review to deliver a precise, low-risk patch. He also prepared clear documentation to communicate the behavioral changes across teams.
