Sorry if this has already been reported but whenever I return to a neighborhood in which multiple missions are being carried out, the "troops deployed" alert sound for however many bars I have going play simultaneously. Since the sounds are stacked and all playing the same thing, I have to worry about blowing out my speakers and/or waking up everyone in the house from the amplitude. I'm sure it would make everyone's experience quite a bit more pleasant to be able to play at a normal sound level without their speakers shaking all over the place. Please make the fix so that the sound plays ONLY once, no matter how many assignments are given.
Again don't mean to re-report as this is a very commonly known problem/annoyance.
