Worked on the OpenTTD/OpenTTD repository to deliver a targeted bug fix addressing cargo waiting time penalties at stations with poor ratings. The solution involved correcting the penalty calculation logic, which previously relied on random generation and led to inconsistent outcomes. By aligning the implementation with established game rules, the update improved balance and predictability in logistics, directly resolving issue #14712. The work demonstrated strong C++ debugging skills and a clear understanding of game development principles, with careful attention to patch hygiene and repository standards. The change underwent thorough validation to ensure stability and prevent regression in related cargo-penalty logic.
