Cannot assign leased aircraft to my routes

[fsimoni]

Hi!
My ID is 3769. I have leased a A320-200 (aircraft ID 109479) from Hampo Brokerage.
Problem is that I can't use it in my routes.
Watching it's info I discovered that it is already assigned to other routes that I cannot close.
Other planes I leased before were free of any routes and I have always been able to assign them immediately to my routes.

Is this a bug or is it just a matter of time to wait for the aircraft to become available?

Thanks in advance.

That... is strange.

I think i know what it was associated with.

I closed the routes.

Now it works.

Thanks a lot.
