I have a 2D sprite animation with 15 frames (@30FPS).
I want to delay the animation (reduce speed), so each from is played twice, so the total animation is 30 frame.

In the hit box editor, I have set the speed to run at (0.5) and created hit box maps for the entire 30 frame animation (now artificially playing slower).

However, when I assign the animation to a move, only the first 15 frames are shown in the preview and animated in game. I have changed the FPS architecture to 30FPS in the "general tab" but that does not change this behavior.

I think there is something wrong with the way I have configured my animation/hit boxes/move, but I do not know what it is. Please advise me on how I could make the move play the entire 2D animation at (0.5) speed with a custom hit box map.
Thank you.
