I think undo - redo deleted part of an action.
I am not sure exactly how to recreate this. I was working with an action. I went back a couple steps using undo. Then I used redo to get forwards again. After that, a large part of my action (an if and the action nodes inside it) disappeared.
I was able to restore it by selectively undoing some steps.
After a short while it appeared again a second time. At this point I had two instances of this part of the action.
I deleted one of the instances and continued working. After a while the instance that remained stopped responding, meaning, I minimized it and am not able to expand it again.
I kept the tab open, and opened the same action in a new tab. Here this part of the action is missing again.
I don’t know how to recreate this, and I am not looking for a solution for this specific case. I am reporting for the sake of preventing this behavior in the future.
I will attach an image of this action in each tab.
