This game uses real time, non deterministic physics engine. Fast Forwarding could result in less precise simulation and thus different even more unpredictable result.

It's a freaking game. What happens with the physics is decided the moment you place those bridges, not determined by whether you're fast forwarding or not. Did I just get trolled?

As I told you. This game doesn't use deterministic physics engine. Physics is simulated real time as game progresses (plays). Because of fluctuations in frame rate, caused by everything happening on your computer, time step taked for physics simulation differs from step to step. Because of this running simulation at faster speed will result in worse simulation.

You can even experience it by running simulations multiple times. You will notice small difference between runs. Those wold be multiplied when run with bigger step (faster simulation).

The physics engine should be based on fixed time-steps (probably 1/60s, because the most common framerate is 60, followed by 50), not be jeopardized by fluctuating framerates and/or slow computers.
