Reproducible with - 2018.3.0a4, 2018.2.0f2, 2018.1.8f1, 2017.4.7f1, 2017.2.3p2, 2017.1.4p2
Does not reproduce with - 2018.3.0a5

Note: there's an interesting thing if you were to disable TestCraft > Body-6 > PartGroup-6 > Apex I-32 > Nozzle > Collider and BottomCollider GameObjects, the game works just fine and nothing collides, ever.
