Hi all, some clarification around the issue with Steam support:
Steam client support was switched off due to a change in configurations, happening during the division of products in the Wargaming/Lesta separation. Steam support should already be back - please let us know if there are any further issues and we apologize for the inconvenience.
In the game client selection screen, you should be able to add a game client if it isn't detected automatically. First, find the folder that your WorldOfWarships.exe is located in (default Games/World_of_Warships), and select that folder in the "Add a game client" menu.
