Worked on the acemod/ACE3 repository to improve headless client reliability by addressing a critical bug in group ownership transfer. Focused on SQF scripting, the developer updated the setGroupOwner function in fnc_transferGroups.sqf to use the correct _idHC3 identifier, ensuring that groups are consistently assigned to the intended headless client instance. This change eliminated a transfer typo that previously risked misdirected group assignments, thereby enhancing automation reliability and reducing the need for manual intervention during headless deployments. The work demonstrated attention to detail in scripting, code review, and Git-based change management, contributing to more robust deployment workflows.
