Sorry that I have to come back to this. I wanted to try the fix, but the 
current nightly snapshots (today and yesterday) seem to be lacking the SUMO and 
SUMO-GUI executables, while netedit.exe is still available in the bin Folder.

Betreff: Re: [sumo-user] Using flows after loading a simulation state
 
Hello Jakob,
the aforementioned bug is fixed in the latest development version. When loading 
simulation state that contains flows, make sure to load the original route 
files that were used when saving the state. You do not need to manage begin and 
end time as this is handled by sumo. Just define your flow as 

<flow id='South_to_North_Car_0' from="-2000000.0.00" to="-2013000.186.34" 
begin='0' end='3600' vehsPerHour='1800' type='CarDistribution' 
departLane='random' departPos='base' departSpeed='max'/>
regards,
Jakob

Hello Jakob,
yes, this is a bug (https://github.com/DLR-TS/sumo/issues/3971).
It should not be necessary to load flows again after saving.
Thank you for bringing this to my attention. 
regards,
Jakob

Hello everybody,
I’m already bothering you with my next question. I tried creating a saved 
simulation state and reloading it afterwards, which works in principle, but it 
seems I can’t use flows afterwards anymore, but would have to define every 
vehicle explicitly. Is that correct? 
A part of my demand definition looks as follows:
This would be before saving the state:
<flow id='South_to_North_Car_0' from="-2000000.0.00" to="-2013000.186.34" 
begin='0' end='100' vehsPerHour='1800' type='CarDistribution' 
departLane='random' departPos='base' departSpeed='max'/>
And this after:
<flow id='South_to_North_Car_continuous' from="-2000000.0.00" 
to="-2013000.186.34" begin='110' end='3600' vehsPerHour='1800' 
type='CarDistribution' departLane='random' departPos='base' departSpeed='max'/>
So basically, I got the same flows again with a different name and create more 
vehicles after the state is loaded. However, I receive an error message that 
the first vehicle with the ID South_to_North_Car_continuous.0 has no valid 
route.
Is this a bug or is it simply not possible to create flows after the simulation 
has already begun?
Thanks
Jakob
