Bug: Particle's Vel/Life causes position shift

This is the latest 4.3 version, straight right from Epic.

I can already see some shift in your image. Notice how the first particle isn’t spawning from the object, but from some position ahead of it? Try rotating your emitter without “using local space” option, and the shift will be more visible.

If you still can’t replicate this, I’ll send you my mock up scene tomorrow.
