In the most recent version or two of World of Warships, there is a new feature called 'Arsenal' which serves as a sort of in-game store where you can spend in-game resources to buy things.
When in the 'Port' screen (the main screen you're at after loggin in) and clicking 'Arsenal' in the upper left corner, one is presented with a sort of loading/busy indicator which never goes away. The arsenal never loads.
How many I go about helping you debug this?
