I'll try to explain what's going on.
In the FSM Start of my scene, The Player is already positioned. I move around in the game then leave the stage.
When I leave the scene, the coordinates are saved.
When I restart the scene, my program knows that it must position the Player at the new coordinates, which it does correctly.
But at this moment, I can no longer rotate the Player on itself. It seems to rotate on the axis of its previous position!
However, I have another FSM which allows me to transport the Player to defined coordinates and it works quite well.
I simply use Get Position and Set Position set to Self (On world does not improve)
