This has been like this since before the patch. I have a two members where they haven’t logged in/played a battle for ages (or so says the game) yet they are rank 12 or lower on PVP.
One member it says 43 days since last battle yet PVP rank 12.
Another is 48 days and rank 9 in PVP.
Now either their battle log is wrong or their PVP is wrong. The PVP stats haven’t changed since this bug started, regardless of the new PVP refreshes.
