Description of the bug

When crowdsim is setup for a simulation with multiple floors, the human models don't show up in the simulation despite including "use_crowdsim:=1". If I remove the additional floors and only keep one floor, crowdsim works as expected.

Steps to reproduce the bug

Launch the simulation with crowdsim as instructed, but make sure to add additional levels to the simulation. I have a custom simulation I made, and I can confirm that crowdsim is working when there's only one level in the simulation, but not working if I added another level in the simulation.

Expected behavior

Crowdsim should work in a simulation with multiple floors.

Actual behavior

No response

Additional information or screenshots

I don't think this will make a difference, but I didn't add any human lanes in the additional level.

Sorry, actually, adding human lanes in all floors solved the problem.
