Sure. I didn’t save the project, so I redid it and captured the whole thing. It only takes about a minute to reproduce.
I run the game a couple times. Notice the incorrect behavior is only after I have copied and pasted the JumpEnd state. This was using the ThirdPersonExample in 4.17.2, but can be done with any project in most any version.
Not sure where to host the video (since mp4s aren’t allowed on here???), so here it is on Google Drive
For more clarity of the effects of the bug: When a state is copied and pasted, all “Relevant Anim” functions cease working for the original state (in this example, JumpEnd). Any of those functions still work for the pasted state, just not the original. So functions for JumpEnd_1 work, but not the original JumpEnd. This continues as long as the pasted state exists, as shown in the video.
