Bye Bye Achievement Broken?

[Sgt.Waffles]

I got one vehicle to the other side of the bridge, but it just keeps on going and the level doesn't end or give me the achievement.

Got the same problem.

Same for me, which leads me to the suspicion that the "Stubborn" achievement is broken as well. Bridge Constructor Medieval actually quit the level when units failed to cross, Playground just keeps running, thus not triggering the achievement.

I just unlocked "Bye Bye" legitimately, partly by accident. It was on island 3 (Southern Reef), bridge 4. Although one of the trucks keeps running at the bottom and the simulation does not end, the achievement pops as soon as one truck touches the ground and the other reaches the other side. I'll try to upload a screenshot.

Got the "Stubborn" achievement in the same level with the same bridge, so it's doable :)
The above solution does not always work for "Bye Bye".
