This is similar to this ticket.

Attached is a 4.24 example project.

Reproduced in 4.23.1 CL#9631420, 4.25 Preview 3 CL#12129346, 4.26 CL#12123513

Steps to Reproduce

1. Create Particle System that has Ribbon Data and follows source particles that are orbiting a point. Make sure to enable "Use Local Space" in both Required modules.
2. Add a particle system component in a blueprint.
3. Set the Template to the Particle System you created.
4. Scale the component to 0.2f or 1.5f in the X, Y, Z.

Result: The ribbons don't follow their source particles.

Expected: The ribbons follow their source particles.
