Animation Montage Not Translating Correctly

So, I’m animating a character to operate a rowboat. The preview meshes are all translated correctly in the Rowboat’s viewport. Here:

However, when I run the code in GAME MODE, the animation montage is in the complete wrong location:

When I try to translate the location of the preview mesh, only the ROTATION is altered, not the location:

So he ends up clipping through the mesh. No matter how high I set him in the preview mesh, he keeps spawning at the same altitude. Here is the Rowboat’s BP:

(Also, the idle montage play ONLY ONCE while he is in the boat. Then he disappears, while the boat is controllable. But first things first!)
