Have you tried to change any of your sensors recently?

I'm not saying you did, but if you tried to add some dB gain to your dome and hull arrays by using some values from the towed array, I could see accidentally setting a bit somewhere that makes those sensors act like a towed array.
FWIW, I'm not against playing around with some edits to see what happens. This was how we figured out what was going on in the exe file and flight dynamics files for different versions of Flight Sim (back in the day).
