- Mod merge: rebuild a merged bundle's chunk metadata the way the game writes it (one record per chunk, in chunk GUID order), so costumes from different mods built on the same game costume keep their textures and meshes - Merge audit checks that layout, and there is a new unit test for it - Server names: only letters, numbers, spaces and - _ [ ] ( ), 1 to 64 characters; the server browser hides servers with other names - New Centrix tag from the backend's "centrix" list: blue and white name, badge and item animation, ranked after Dev and before Creator
