SOLVED

So I am trying to get a bridge objective working. The bridge in question rus_bridge_road_01_objective, has 3 stages. build_stage_0, build_stage_1 and build_complete.
I want to go from stage 0 to stage 1, in the first part of the mission and then from 1 to complete on the second stage.

The closest I got it to work was with the setup below. Which actually did the animations of 0 to 1 and 1 to complete on delivery. However before even starting the mission the game would randomly show the animation from stage 0 to 1, everytime I drove over a zone, another mission zone, or a pickup zone.

What am I doing wrong? Or is it bugged?

I did not get errors with this setup.
