Odd stretching with cloth asset

When simulating in viewport, a section of the cloth asset stretches out far into the distance.

So far I was only able to reproduce this with the CLOTH_SimpleCloth asset in QAGame. The cloth in Content Examples worked correctly.

I wasn't able to reproduce this in UE4/Main or UE4/Release-4.14.

1. Open QAGame in editor.
2. Add CLOTH_SimpleCloth to the level.
3. Simulate in viewport

RESULT:

Section of the cloth stretches indefinitely.
