Ok, so I checked “Pawel i Beata” and “Raging Titans”. Their match is ok based on the rules they got in the AB test. This is the part that we are still working on and here is plenty of discussion about it in Alliance Wars Matchmaking (Discussion & Developer Response) MASTER - #644 by Crusher19680
However, the case of “inSanidimente” is very interesting. This is a corner-case where 7DD was matched near the end, and your alliance was the best one that hadn’t been matched yet. This problem doesn’t affect 99.99% of the matches but it is a valid problem and I apologize for that.
I’ve created a separate ticket about considering how to avoid a case like this in the future. I’ll leave the thread open, but will consider it closed myself, i.e. will not be commenting more here.
