Particle Ribbons not firing off consistently

Ribbon trails do not immediately follow the lead particle when fired. There is an inconsistent delay in some that cause them to either not fire or fire mid stream.

This did not occur in 4.10.4, but has become an issue with 4.11 and 4.12. I've attached comparison videos below of the behavior in 4.10 vs 4.12 Dev Rendering CL-2936939

1. Open Content Examples Effects map
2. Go to stand 2.5 or open the PS itself with P_Ribbon_Trails

Regression: Yes

Results: Ribbon trails do not always fire immediately

Expected: Ribbon trails should fire off when the lead particle is shot

Ribbon Emitter works in editor but only 1/10 times on IOS

Ribbon trails only show in editor, but not in game build

Ribbon is spawning very late
