I deleted the old plugin first and then imported the latest version.

When are you seeing this error, looks like it’s during runtime when an agent is moving?

Hi

Are you able to reliably replicate the issue?
If so, I would be very interested if you would want to share a test project where I could replicate it.

I downgraded for now. But i’ll try again during the next days.

I was able to solve the problem. Since I’m using a Baker and System and not FollowerEntity, I don’t know if the result will be useful to anyone else.

The reason was that the latest version was running FollowerControlSystem before my system added the ‘ManagedState’ component.
I add the ‘SimulateMovement’ component now in the System instead of Baker.

The change is also available here:
