Worked on the cmss13-devs/cmss13 repository to address targeted backend issues in Army Roles and Unit Classification within the Tyrargo Rift game environment. Focused on resolving a bug that affected US Army Synthetic Survivor token access and the classification of the 32nd Armoured Division Tank Crewman, the developer delivered a precise patch using DM for backend game logic. The solution involved updating role logic to prevent misclassification and unauthorized asset access, with thorough validation against gameplay scenarios. This work improved player experience by ensuring accurate unit classification and asset retrieval, demonstrating careful attention to reproducibility, documentation, and end-to-end testing practices.
