Aircraft selling
I was trying to sell a 747-100, put 12 million into the custom price, pressed the 'put on market' (or whatever it is) button, and instead of being placed on the used market with my price, it sold to the broker instantly for around nine million. A few minutes later I sold another 747-100, put 12 million in the custom price box, pressed the same button, and it was put on the market with my custom price. Basically, one of those times the plane was sold to the broker for the instant sale price instead of being placed on the market with my custom price, and while here it was only a ~2.5 million difference I can see this being a much problem if it happens with more expensive planes.
