When certain tasks or contracts are completed, the "soft" barriers are not removed from the game. The safety cones are generally not an issue, but the Type 3 barricades (which now must be driven through) cause truck damage. This can be minor wheel and suspension damage or hefty engine, wheel, and suspension damage. It seems to be determined randomly based on speed and angle of impact.
The most notable example of this is beneath the repaired pipeline on the Mountain River map in Alaska.
Is this intentional or a bug?
