Worked on stabilizing core calculation logic in the SpectralPack/Cryptid repository by addressing a critical bug in the LeBaron James enhancement calculation. Focused on Lua scripting within a game development context, the work involved implementing nil-safe checks to prevent crashes caused by unsafe access to the rank key. This approach improved code defensiveness and reduced the risk of production downtime or user disruption. The solution preserved existing behavior while enhancing reliability, and the change was reviewed and merged with minimal risk. All updates were linked to relevant issues for traceability, reflecting a careful and methodical approach to bug resolution.
