Reproduction steps:
1. Open the attached “IN-114121.zip” project
2. Open the “ClothTest” scene
3. Enter Play mode
4. Observe the 3 Cloths arranged from left (low-poly) to right (high-poly)

Expected result: All 3 Cloths stretch and behave the same
Actual result: Cloths on the right stretch significantly more, like a spring
