Ugh, So sign errors are the worst. I had this happen when I was working on a physics simulation, and it turned out to be a misplaced negative sign in my initial conditions.
One thing that helped me was writing out the equations on paper and comparing them to the code. Sometimes seeing it visually makes it click.
Also, if you’re using matrices, double-check your transposes. That’s a sneaky one that can cause sign flips.
