Planning dependences start-start

It still didn't work.

I realised that the milestone was scheduled at the begin of the last sub activity of "Non-Regression Tests".
I made it depend "start-start" on the first sub activity of "Non-Regression Tests", and it worked. But it's not really what I wanted to do, because this couldn't change in time.

It seems the issue is related to the fact that the precedent activity contains sub-activities.

I'm not sure if what I wrote is clear....
