Mind-Brain!!! I have good news.
I also deleted the wait node on the right and tried to return it to the old form. As you really said, the Target Chase node was not connected. I didn’t even know it was disconnected because of the annotation..
And importantly, I found out that if the nodes are not connected, they appear dark gray.
When I checked after play, if the node is not connected, the red bar appears, and if I connect the node, the red bar does not appear.
Thank you so much. Thanks to you, I solved my troubles and I learned a lot!
