Worked on the Hearts-of-Abexilas repository to address stability issues in the simulation’s population dynamics, specifically targeting Werselis Island. Focused on data management and game design, the developer implemented a precise bug fix that reduced the simulated population from 23,550,000 to 2,355,000, directly mitigating overpopulation and resource contention within the five-province island. The change was executed in plaintext, ensuring clarity and traceability through a single, well-documented commit. Updated reference documentation provided context and rationale for the adjustment, supporting reproducible builds and future tuning. This work improved simulation stability and established a foundation for safer ongoing development and testing.
