Problem with the player trying to use an object while the dev debugging it

As the title say, there is a problem with the player trying to use an object (in my game it was a flightpath) while dev closed it for debugging, and it cause the player happiness reduce. But the thing is the player keep repeating it until their happiness reduce to negative and end up unsub with the reason '<<name>> is offline'

Thats actually a result of a old bug. All players try to use the transport again after a failed attempt (specially if its the only way to a zone). If it fails for any reason (not enough gold, or not willing to pay amount, closed, bugged, disconnected). The player will keep trying. Losing happiness and addiction. And unsubbing when it reaches -5.
