Chris contributed backend development and bug fixing to the Rotwood-Vale/Ratwood-Keep repository, focusing on gameplay systems and data integrity. During April 2025, Chris addressed two critical bugs using DM, targeting Byond 516 compatibility. One fix restored test merge link behavior to open in a new window, preserving chat history and ensuring reliable test interactions. The other corrected crafting logic so that remaining items from bundles are properly returned or dropped, maintaining expected crafting flow and materials accounting. Chris demonstrated regression debugging and gameplay logic validation, delivering targeted improvements that enhanced user experience and reduced data loss risk within the game’s backend systems.
