@timja Do you have an idea why the output is p1s2 without a time on Windows 21?
I even did not found the code that produces this part.

Optional[  * Simple Stage *(15 ms)*
  * In parallel *(0.15 sec)*
    * p1 *(15 ms)*
      * p1s1 *(32 ms)*
        **Unstable**: *something went wrong*
      * p1s2
    * p2 *(15 ms)*
  * Fails *(31 ms)*
    **Error**: *a fatal error occurs*

@timja I removed the guard as FlowGraphTable.Row correctly handles the case where duration = 0. This makes the test run on all platforms now.
