+                What this will do is IF the redirect seems to be "dead" it will create a builder and essentially populate (flatten)
+                all the children from the dead redirect to the node.
+
+                So, if minecraft:msg redirects to msg but the original msg node has been overriden minecraft:msg will now act as msg and will explicilty inherit its children.
+
+                The only way to fix this is to either:
+                - Send EVERYTHING flattened, don't use redirects
+                - Don't allow command nodes to be deleted
