Steps to reproduce:
1. Open "TestStartOrder.zip" attached project
2. Enter play mode
3. Observe trail sometimes working, sometimes not

Expected result: Trail is always created from the sphere start position to the end regardless of interpolation
Actual result: With Interpolation trail sometimes gets created, without - it never gets created

Doesn't reproduce on: 5.5.4f1, 5.6.0a1, 5.6.0a3, 5.6.0a4
Regression introduced in 5.6.0a5
Reproduced on: 5.6.0a6, 5.6.0b1, 5.6.0b8, 5.6.1p1, 5.6.1p4, 2017.1.0b10, 2017.2.0a4

Notes: Setting even the tiniest amount of in-between motion delay makes the trail function properly
