If you change Timeline from non looping to looping it still says the script is compiled.
if you start your game, timeline still does not loop until you recompile your script.
Timeline settings do not affect “Compile Button” in Editor!
Hello mZe84,
Thank you for reporting this issue. I’ve reproduced it and it seems like it doesn’t dirty the blueprint at all, this also extends to the other settings such as Length and the other checkboxes. I’ve placed a bug report in and you can find it here: UE-40674
Have a nice day!
