I have the same issue, and have tracked it down to the new folder created in the Replays folder, i.e the game version now appears, see screenshot.
So replays are now stored in "C:\Games\World_of_Warships\replays\0.8.5.1", if you start a game, and then copy the "temp.wowsreplay" files, there are 2 others I can't remember off the top of my head to the "C:\Games\World_of_Warships\replays" you get game data.
It works but not practical.
I would be useful to be able to select the replays folder directly, rather than let the MM software "find" it.
Just my 2 pence.
