Hello Yade devs and users,
I have a question about loading a saved model and change the engine behavior.:

I followed the example in https://github.com/yade/trunk/blob/master/examples/triax-tutorial/script-session1.py
At line 160: O.save('compactedState'+key+'.yade.gz') I use O.save('mymodel.xml.gz') and then I have the file mymodel.xml.gz in that folder, I stopped there and turn off yade.
Next time, to continue my simulation I run this script to continue, as a normal triaxial test:

from yade import pack, utils
O.load('mymodel.xml.gz')
triax=TriaxialStressController()
while 1:
  triax.stressMask=5
  triax.goal2=-0.01
  triax.goal1=100000
  triax.goal3=100000
  O.run(100,True)
  print 'p=', triax.meanStress
  if triax.strain[1] < 80000:
    break

but I see that when I run that script, in the terminal, the output of triax.meanStress is 0.0, and the TriaxialStressController is still continuing to use stressMask=7 with goal=100000 (I used Inspect tool from graphic interface) as saved from previous simulation. It seems that my code didn't affect the model at all.
I tried both
yade-stable myscript.py and yade-stable then execfile('myscript.py')

Can you explain this for me, thank you!
