For the past day or so, I've been having an issue where calls do not come in at the frequency specified in my settings. And now, I'm not getting any calls at all. Yesterday, when set to get a call every minute, I got a call every minute. Today, when set to get a call every minute, about half the time I'm going 3-5 minutes or more with no calls. So I bumped it up to a frequency of 1 call every 30 seconds, and calls often come in 1-3 minutes apart. I've just started playing yesterday (after finding out about this game on the fire911.net forums), but I've already got one fire station with 3 engines, and one police station with one patrol car. I feel this should be enough to maintain a frequency of one call per minute, but it seems that's not the case.
