Line attractor not working in scene

Hi all,
I’m having a problem with particles and the Line Attractor. In the particle editor it works fine, but in the scene it doesn’t. I’ve been playing with the parameters of the line attractor, but nothing changes. I’m really lost with this :S
Googling I found nothing :frowning: anyone knows what’s happening? I’m using 4.12.5
