I first came across this bug when I was working with Actor Sequences and noticed that the door I had opening would snap back when I tried to close it. Later I discovered that the issue was with playing sequences in reverse.
This also happens when Play Rate node is used and the value is set to -1
This is a Regression from 4.14.2
NOTE The "snapping" effect only happens when you wait for the sequence to finish opening the door completely. If the actor exits the trigger before the sequence is over, the door will close as expected.
This is tested in UEQATC-1583
Result: The door snaps back closed and does not play the sequence in reverse
Expected Result: The door slowly closes as the sequence plays in reverse
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-40076 in the post.
