Thank you, it works as expected!

Maybe it would be helpful to get a warning that the seed argument does not have any effect in this case (or to ignore 'rngState' and 'rngLane').

This is just a note for a future release. My specific problem is solved.

Hello,

You may remove the elements 'rngState' and 'rngLane' from your state file before loading it with option seed.

regards,

Jakob

Dear Sumo-Team,

I have the following setup. I need to save a specific simulation state (with the option "--save-state.rng" for reproducibility)  and load it again.

Loading the saved state works well. 

However, sometimes I would like to load the saved state and need randomness. Thus, I provide the argument "--seed" upon loading.

However, the seed argument seems to have no effect (no warning is issued either).

How can I load a state (that was saved with option "--save-state.rng") and provide different random seeds?

I am using SUMO 1.9.2 running on Windows 10.

Thanks in advance.

Sebastian
