data. Saving a file with a new blender node that uses bNode->storage data and then loading that in an older version will make the node undefined, but still retain the original type identifier (in case it is defined later). If the file is then saved over and loaded again in the newer version, where the node type is defined, it won't have a valid storage struct. To handle such cases gracefully, check if storage data is expected but doesn't exist when initializing node types. User then at least get a chance of fixing the problem manually.
