Premium Member Issue

Hey everyone! So i'm not sure if anyone else has noticed it already or maybe i'm over thinking it... But for us members who are paying the 34 coins a month to be a premium member, I've come across an issue with Calls being spawned in the timely manor that they're suppose to. I love keeping my mission speed set to every 20 seconds, however lately they have been taking much longer than 20 seconds! Today it got to the point where I timed the incidents coming in and here is a brief example of what it looked like. In 2:57 I received 5 incidents when in reality it should have been atleast 11 incidents spawned.... I'm not sure if this is a bug that needs to be fixed or what, but I'm speaking for the members who haven't mentioned anything yet that is going through the same issue. We are spending money on this game and being a Premium member does benefit when you run an alliance and have a handful of guys working in it. Being able to track everything and everyones work is great! Just didn't know if this is something that needs to be looked at! Other wise keep gaming on everyone! I've been playing for about 2 months now and have an extremely active alliance with over 20 active members and earned over 10,000,000 credits! We don't plan on stopping anytime in the near future.
