Hello!
Type: Negative Gate Value
Airline Details: Buddy Airlines - ID 22786 [W3435]
Description: I have found the similar issue like this one,
http://stephenm.org/smfforum/index.php?topic=13519.0I have been away from the game for around two weeks,
in the overview page of the airline, I found that one of my focus cities, La Guardia (LGA) Airport is missing from the list,
when I was trying to open a new route from LGA, I got a negative value on gates (-81).
My gates are 'Build Terminal' type.

Negative slot value can be found in 'Extend Terminal' page.
Thanks!
