This BO is my first BO from Navyfield BETA, along with the 10/10 gunners. I have mainly played DD vs DD or DD vs CL rooms, long before Blitzkrieg or Great Battles and stayed in my beloved z99 (before it was nerfed and NF took away the 6.75D guns) until mid 70s level, without premium, so as you can imagine the XP for a BO in the 70s was pretty low, it took a long time to level up but it was good fun. Never played any other nation but Km, only have one other BO and no CVs. And I don't think anyone could sink 10k of any ships before reaching level 60.
I have stopped playing for a while and when my account got reactivated I started at zero games played and got kicked out the Hall of Fame, so yes, 2,500 games is way too low.
There is a timestamp in the screenshot - it was 12:38. I honestly do not know what happened to the NF version number in the screenshot.
The only thing fishy here are the fishes in the sea.
