in Simulation 0
in agents vehicle_following_path0, Simulation 0
in do drive ;
in reflex commute when: current_path != nil  {
    do drive ;
}

To Reproduce Steps to reproduce the behavior:

2. Load it
3. Press play
4. See error

I tried on a few computers and turns out it only happens on mine. I tried on a mac, a linux, another windows, so the issue is probably not (only?) windows. I also tried on new workspaces and with the eclipse version of gama as well as with the release with the same result. Maybe it's my cpu ? here is the result of gama.info:

additionally I have the same problem with 1.9.3 so it's not linked to the upgrade of jdk/eclipse

I have it on git version, win OS (not tested on Mac)

What's your cpu on this computer ? Is it also an amd ? could you post the result of the gama.info command ?
