Map: NEW DAWN
Location: The island at i5
Ship: Miyogi
Situation:
I am on the western side of the island, heading south.
Enemy torpedo bombers are approaching from the east.
I increase speed to move the island between them and me.
As they drop the torpedos, they are still on the eastern side of the island.
But the torpedos appear in the water on the western side of the island.
Even though I'm extremely close to the island, maybe 50m to 100m.
It broke immersion, felt very unreal.
Conclusion:
Islands should provide protection from torpedos.
There should be a certain amount of straight water surface beneath the torpedo bombers for them to successfully drop the torpedos.
