Cannot execute the command: ScreenplayTraits.GetVersions
 

I am running batch simulation on HPC. When I try to connect to my simulation, I see this error.

"cannot execute the command: ScreenplayTraits.GetVersions" This was not happening previously. And does not occur everytime for every simulation.

Once this message pops-up, I cannot see the simulation tree. So editing the simulation is not possible anymore. Can someone help me to fix this problem?

Thank you.
