WIP TESTER BUILD - active development and live in-game validation are incomplete; use backed-up test worlds. Rig-visibility hotfix for the RX-79[G] Gundam Ground Type and Zaku Mk II Heavy Desert Type: transmits installed suit parts, explicitly attaches rigs on clients, and retries initial animation loading while retaining server-authoritative combat and cockpit systems for Project Zomboid Build 42.20.4.
