    Hello. How to get rid of nullref? The object is assigned in edit mode, so it's definitely there. upload_2022-8-9_18-17-8.png

    Perhaps logic elsewhere sets GamePanel variable to null? Does GamePanel still has the value there at the time of error?

    No, the object is definitely not destroyed. I tried to add the "Null check" node, the error is fixed, although I'm almost sure that I had already tried checking for null before and it didn't work, maybe it worked because of the Unity version change.
    In general, the problem is not in the nullref itself, but in the fact that FSM changes state on exit from game mode, this can cause many harmful effects, such as saves damaging.
