Reproduction steps:
1. Open attached project "1369087.zip"
2. Load the "Main Menu" scene.
3. Observe the GameObject "Collectable Area > Diamon Area > Log".
3. Enter Play mode and observe "Log" doesn't sink far
4. Select Edit > Project Settings > Physics 2D > Job Options
5. Disable "Use Multithreading"
6. Enter Play mode and observe the difference of the "Log" obejct.

Expected results: The "Log" object should sink in a similar manner whether "Use Multithreading" is on or off.
Actual results: The "Log" object reacts significantly different depending on whether "Use Multithreading" is on or off.
