    Spring.ForceUnitCollisionUpdate(unitID)

    Prevent collision checks from working on outdated data There's a rare edge case that requires units to be in specific positions and being shot by specific weapons but which can result in shots ghosting through the unit.

    This is because the unit's collision volume is stale. The `movement.unitQuadPositionUpdateRate` modrule controls this behaviour and can guarantee 100% correctness if set to 1, but the default value is 3 and large-scale games generally don't want to set it so low. This function lets you guarantee success for important weapons regardless of how high the normal update rate is set.

    Parameters:

    1. unitID number

    Returns:

    1. nil
