That requires a bit more studying on my side; I'll get to that immediately after finishing those 3 open papers :) > Moonshoot: Do you by chance insert RNGScope instances?

I guess I'll rely on the seed being set in R for now. BTW, I can now confirm that the issue appeared during the transition from 0.10.6 to 0.11.0. I really hope to be able to provide some more information some time soon.
