Don't believe that this is merely a glitch - I qould be willing to bet that if all players were to buy the aircraft they are leasing, a lot of players would discover that there are planes they do not operate but are paying leases on - I actually checked this by going to three different game worlds (O2, Ralpha, and S-3b) and buying out all my leases - in all three of them i found a few aircraft that I quote - do not operate - unquote, but in the finance section showing aircraft leases i am showing that there are a few planes that I am paying leases on, but cannot buy or terminate leases on - in other words, i am not the owner! So how is it that I am stuck with lease payments on aircraft i do not own?
The only way to discover this is to attempt to buy out all your aircraft.
Thus I am pretty sure this is a lurking bug which has been present for some time, but since the majority of players never buy their aircraft, means that they have not been aware of it.
But it may be the case that there are several players who, like me, are actually paying leases for planes they do not currently own.
Thus I hope to gain yuxi's attention to check into this.
If I had to guess the source of this error, I think that in the course of trying to lease used aircraft, when several players are trying to obtain the aircraft at the same time, the code is unable to track parallel activities and correctly assign ownership.
Thus the code may actually assign ownership to one player and actually charge the lease payments to another player.
This would unfortunately, be a spectatularily difficult bug to fix, so I hope I am wrong, but I have that awful feeling ...
