Hi Alexandre,

I think the problem here is that you have two ways named "RUA PORTO ALEGRE",
one with id 2, the other with id 46, and both are in the same city.
So far no problem, but the addr:interpolation ways on those two roads
also produce a bunch of duplicate numbers.
As a result, the new algo decides to ignore them.
Unfortunately, the log

is not very clear about the reason and the final action, but I think the data is not okay and the algo is correct
to ignore it.

What do you think?
