During June 2025, Konrad Jonek contributed to the OpenTTD/OpenTTD repository by focusing on reliability and user-safety improvements in core gameplay tooling. He addressed two critical bugs using C++ and his expertise in file management and GUI development. Konrad implemented item-type validation in console commands to prevent accidental deletion of non-savegame files, adding user-facing error handling to protect user data. He also refactored the station joining workflow, ensuring the station selection window appears correctly in tile-gap scenarios and improving the maintainability of station discovery logic. These targeted changes reduced data loss risk and established a robust foundation for future enhancements.
