Atago = 100% of games bugged
Myoko = 90% of games bugged
Blyskawitsa = 70% of games bugged
ARS NOVA CRUISERS (Nachi, Takao, and Maya) = 100% of games bugged
ARS NOVA BATTLESHIPS (Haruna, Kirishima) = 0% of games bugged
From my tests, it definitely seems like torpedo launchers are the problem.
Emphasis on *launchers*.
I play a lot of CV game play and ive never had this bug in a carrier. Either im lucky, or it has to do with the launchers themselves, not the actual torpedo. Because my Arial torpedoes have no issues. Thats the data ive found. All of this was running on Low for testing (besides shadows cause a game without shadows is yucky)
