Bug occurred on public Beta v.0.4.0-18467+s207

I have been playing BOTA #1 custom scenario (requiring some mods from workshop like custom Royal Navy units i.e. Type 42 DDG). At some point in the game i fired a spread of Mk48 torpedoes at the enemy ships. From this moment the game started to behave weird:

1. AI instantenously counter fired at my torpedoes with their SS-N-14s
2. All of the enemy ships disappeared from the map view and became undetectable for the rest of the game
3. in 3D view enemy ship models still were present and continued on course they've just disappeared from the map
4. Log was spammed with messages about null ref exception

I tried saving and reloading the game to check if this would fix the issue but save function threw yet another error.

Ended up quiting scenario as it became unplayable with enemy units undetectable.

Regarding points 1. I dont really believe they should be able to counter fire torpedoes that quick. Its not like SS-N-14s are fired automatically like Aegis controlled missiles are against ASMs. There should be a human factor and decision making process simulated and a considerable delay added since the torpedo detection till counter firing.
