Looping object movement in blueprint offseting when not at 0,0,0

Here ya go:

I suggest that you also set a new over time, 0.2 will make your rock go hyper speed. Best practice is to make a new float to hold the over time, set it default value to some value you want, then feed it value to the Move component node, so instead of having to edit at least 2+ values, you only have to edit 1 value.
