Reactor "the body became unstable" error problem

[fiori]

What im trying to do is to roll some spheres into a bowl kinda thing, the settings seem fine but anytime im using reactor on this file the thing just goes nuts. as soon as the sphere touches another rigid body it flies off in anotehr direction, rather than rolling down as it should. I get the error message "the body became unstable during simulation; transforms from that time havent been updated" when I do it as an animation (i.e not as a preview) and I been trying to figure it out for ages but I dont know why it wont work on that file, and I need to work on that file so it has to be done on there and merging the file into a new one doesnt work either, any help would be great

I managed to figure out what was wrong, for some reason the world scale and collision tolerance was set too high, I never changed the settings so dont know how that happened, but all is well now
