therickman it does appear to be a bug, yes, not really related to the Launch action tho. It's freezing on the last frame of the launching animation.
The launched object seems to be created at the end of the animation, so that's why it stops launching.
Although you don't need to manually select that animation or even start it, it's done automatically once you use the Launch action.Workarounds being: restore animation frame before Launch and it will work as intended.
This kind of issue happens when an animation is forced multiple times in a very short period.
If the animation frame plays for too long without proceeding it automatically forces it to stay on that frame.
(Like when you use force animation frame with "Change... > Animation frame", requiring a "Restore... > Animation frame")Please login to see this picture.
Hello, thank you the workaround works.
