2.5 crashes with Harmonics / Boids

Are the Harmonics and Boids being fully integrated in the 2.5?
As soon as I open some 2.49 files Blender 2.5 crashes.
By the way I’ve an old tutorial about harmonics and reactor, but I don’t see the reactor in the 2.5…

in reactor you mean force fields they are in physics under cloth

Nope, I mean that one in the pic below. And by the way I’m not finding the reactor force field in the cloth panel…

IIRC, reactor code wasn’t ported to b2.5 because Jahka was planning to reimplement them in a better way. Same goes for boids (he actually started recoding) but I think old boids code was ported.

So, let’s wait for the new implementation.
