From my friend who plays the game a lot.
After the latest updates, two serious bugs were discovered in the game.
The first is the guns stopping firing, despite the rotating turrets, the presence of ammunition and the presence of an visible enemy. It is not particularly clear why this problem occurs. But it is known that it is solved by switching to a non-firing ship. You can see all this in the video.
The second is the penetration of shells into the deck (fore, main and aft) in situations where there simply cannot be any penetration. As can be seen in the screenshots, the battlecruiser struck the deck of the Spanish battleship from a distance of 12.5 km. But at the same time, the penetration of the battlecruiser shells at this distance is 6'', and the thickness of the armor of the battleship deck is 9.5''.
