Yes,
I get that quite often actually, the fact that an action script is hidden from the main workflow has this down side, I had this big time with the time scale action where I assumed it was just affecting the timeScale, but it also affect the fixDeltaTime, and I was reverting back the time scale by script, the result was a very very slow frame rate, like 3FPS, so I though something broke in my physic set up or a script was going mad... profiler was crashing, I could not find the source, until I had to take it down to pieces until I nailed it...
Bye,
Jean
