Instead of 30 Days maybe one week or two?
I think, letting a contract decay after 30 days is Not the best solution, i would have a better Idea:
Show a Timer, Like we have for contracts wich are waiting for being accepted, how many days it wasnt handeled by anyone.
In top, make a sorting Button for the fleet Manager, to sort for some criteria Like “Last Time handeled”.
So any Player can deside, whats His Personal Deadline and can cancel them very easy.
On top, one very Important Part:
Please WoA devs give us one different Methode to requests Player Connections. I dont want that my stand get blocket, especially at small Airports where you dont have so many Stands.
I think that will be the Most Important feature ever.
