BUG: Non-physical power flow solution returned when simulating MV/LV network about roseau_load_flow

[Saelyos]

I've just tried with current develop branch, and the issue seems resolved : I get the same results, except for the lines 4, 5, 7, that are now coherents :

I could reproduce the bug, it was coming from an incorrect initial potentials propagation. The good results are now always returned, with sometimes even less iterations, so thanks for the report !

Thanks @Saelyos, this is very good news as this issue was affecting most of the MV/LV simulations I was trying to make. Will this fix be available in the next release ?

Yes! :-)
