    One straightforward way to fix this is, is to uptick the current `VERSION` to 3, and here
you do:
    
    ```
    if (getReadVersion() >= 3) {
        // read broadcast state stuff
    }
    ```
    
    so we only try to read broadcast state stuff if the written version in the savepoint is
larger or equal to 3.
