    I'm getting this error as soon as an agent is done in the environment when I use gym-unity-0.14.1 and gym-unity-0.15.0:
    Image.png I think it's because of the update in gym-unity-0.14.1: #3496 .
    BTW, I don't think there're something wrong about my code. Because it runs properly when I use gym-unity-0.14.0.
    Looking forward to your reply. Thank you!

    Sorry for the delay. I can reproduce this error by modifying one of our example environments, so I'll work on a fix today.

    At least for my case, this seems to be due to an Agent calling EndEpisode twice in the same step.

    Thank you sooooo much.
    In my case, the single Agent only calls EndEpisode() once, but the error still appears.
    Maybe I missed something wrong.

    Waiting for the new release!

    Oh, I add "print("success")" after "EndEpisode()". The Agent definitely calls EndEpisode twice in the same step. Because it prints twice.
    But I don't know what's the reason is. I built the environment following the guide in docs.
