I did not see issues with match making on the PT.
I guess this is addressing the Matchmaking in the 0.9.2. I have seen a large disparity in classes, especially when I am VIII and I face 8 ships tier X.
So far the PT wasgreat, not bugs but I have seens a mis-translation in italian.
When 2 friendly ships collied, the user is reported to have "destroyed" --> "Distruzione" and not "Damaged" as in english --> "Danno".
Happy to test in italian but I never swapped the language from english to Italian. If there is an option to swap the language let me know.
Keep up the good work.
