## Bug Fixes - **Fixed MC 26.2 client crash on launch (Fabric/NeoForge)** — `GameRendererAccessor` shadowed `mainCamera` as an interface field, which Java treats as `static`. Mixin rejected the apply with `STATIC modifier of @Shadow field mainCamera does not match the target`. Removed the broken accessor and now use the public `GameRenderer.mainCamera()` method. - **Hardened LevelRenderer access on MC 26.2** — Replaced the same static `@Shadow` field pattern on `LevelRendererAccessor.submitNodeStorage` with a proper `@Accessor` getter so world waypoint rendering cannot hit the same mixin failure. ## Technical Changes - Deleted `GameRendererAccessor` (Fabric + NeoForge) for MC 26.2. - `MixinGameRenderer` now reads the camera via `mc.gameRenderer.mainCamera()`. - `LevelRendererAccessor` uses `@Accessor("submitNodeStorage")` instead of an interface `@Shadow` field.
