I'm not willing to agree to that. While you are probably right about game mechanics, i.e., why deliveries are delayed, I did not complain specifically about it, I complained about deceiving aircraft description, kind of "small print" in nowadays equivalent.
Aircraft page at the time of announcement does not say kind of "Estimated deliveries as of [date here], depending on free slots", so one is aware of possible miss-estimation; it clearly says "First deliveries", so you expect deliveries to start on designated date. Yes, serious delays do occur in real world, but then kicks in the next bug, cancellation policy - delivery is delayed more than 4 years to what was announced, and I cannot cancel it without losing 60% of funds. If I change my mind about the order, ok, I cancel the order accepting the loss; but if "manufacturer" gets in trouble, it's me again who needs to take a loss, really?!
The bug I highlighted in my second post was that delivery date, let it be "estimated delivery date", whatever, is not updated with the pass of time - it is now January 1956, and aircraft page for L1049C says "First deliveries: April 1953". English is obviously not my native language, but I fail to see any other meaning of that message except that first aircraft was delivered to airlines almost 3 years ago - but it's not the case, none has been produced so far! The same goes for other three variants, D, E and G, first delivery is indicated far into the past while no aircraft has been produced, let alone delivered.
Coupled, these two issues tell me that models are not synchronized - looks like a model has built-in time between announcement and first delivery, say 2 or 3 years or whatever, and it is shown in aircraft page; but it does not take into account backlog of previous models. IMHO, it should check the backlog at the time of announcement, and adjust "First delivery" time accordingly, and also keep it updated as the time passes by.
