Bug in O1

Hey! 
For some reason a bunch of routes in O1 are no longer allowing for additional frequencies to be added. Adding flights works like normal, except the flights never actually begin. 
MEX-DTW would be an example, but it is happening all over the map. 

How many idle aircraft do you have? How many total aircraft?

I find that in the late game when my fleet is quite large, and I have lots of idle aircraft, I cannot add flights. In fact, I cannot sell aircraft or even view the used market. I have noted this issue in the bug tracker, but with no reply from the developers. It is almost certainly a server resources issue.

I would be happy to pay for better server space if there was some way to do so. I want this game to stay alive, and the quality does seem to be slowly decreasing.

If you have over 1000 aircraft on the 'add flights' page, the game bugs out and you can't add frequencies. Best way to get around this is to sort by type.
