Here are the most frequent reasons you'll see this warning:

| Cause | Explanation | |-------|-------------| | Corrupted Preset File | The .ad2kit or .ad2preset file you're loading has a broken reference to a bus layout. | | Version Mismatch | The preset was created in a newer version of AD2 (e.g., 2.5.0) but you're running an older version (e.g., 2.1.0). | | Missing Factory Content | You may have moved, renamed, or deleted the default AD2 data folder containing bus schemas. | | Permission Issues (macOS) | On macOS, especially after an OS update, AD2 may lose permission to read its own library files. | | Custom Layout Corruption | You created a custom bus layout that has since become corrupt or unsupported. | | DAW-Specific Bug | Some DAWs (e.g., Pro Tools, Cubase, FL Studio) handle plugin state restoration differently, causing temporary bus layout loss. |

This sounds basic, but corrupted temporary cache files can cause the bus layout system to fail. A full restart clears plugin caches. addictive drums 2 could not find bus layouts
