I couldn't find if this was reported or not, so I'll just report this here. Hope this is the right place!
I snooped around in the WoL folders because I like good music and I've enjoyed what I've heard so far.
Sound -> Wotta -> Music -> Modes.
I found Espionage, which seems like it should be what plays when you get 10 spies. But instead of special music playing when that happens, everyone in the game gets a sound notification and then the music just.... Stops playing.
Is this deliberate? Could be; the silence is eerie and creepy. Is this a bug in the code? Also could be; why include a song literally called "Espionage" and not use it?
