Horizontal Rigidbody2D.Addforce not working, but vertical works fine?

***EDIT!*** So I loaded up a FRESH PROJECT, created a circle and added my script to it. When I hit start the circle launches off at a 45 degree angle, it works perfectly fine. I also tried adding a horizontal addforce on another object in my original project and it resulted in a jittery teleport to the right. Something is broken inside my project related to horizontal force... What could it be?! This has driven me and a bud mad for 24 hours now and I've searched high and low but have not found any similar problems or applicable solutions. I'm developing a mario-style side scroller game and the concept is simple: Hit the box, a coin pops out with vertical and horizontal force. This is the ONLY code so far in the script attached to the coin. void Start() { forceUp = new Vector2(0, upForce); forceSide = new Vector2(sideForce, 0); GetComponent().AddForce(forceUp, ForceMode2D.Impulse); GetComponent().AddForce(forceSide, ForceMode2D.Impulse); } This is the code that instantiates the coin in the box script: private void OnCollisionEnter2D(Collision2D collision) { RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.down, 1.0f, layerMask); if (!isOpen && hit.collider != null) { isOpened(); Instantiate(openPrize, new Vector3(transform.position.x, transform.position.y+1.0f, transform.position.z), transform.rotation); } } problem is: The coin will pop "up" a distance directly related to the value I plug into the "up force" variable. The coin will not move horizontally at all. If I jack the horizontal variable up to some stupid number like 5000, it will teleport a short distance to the side.
