Mesh vanishing when i compile

Hi guys so i have a simple cube with a solitary bone that i use to animate it . Which is made and rigged in blender . I have a simple animation that flips the cube which is a temporary jump animation and is simply there to illustrate the jump animation of my eventual character . However when i add this animation to my anim.bp and press compile the mesh simply vanishes … What am i doing wrong guys ?

You’re probably using wrong scene units which causes a UE4 bug to make the animation 100 times smaller. Check that you’re using 0.01 metric unit scale with applied transforms (1.000/1.000/1.000 in scale for both the rig and the mesh).

HMMM nope mesh still disappears This has to be down to something stupid that i am doing wrong
