I don't think it's a bug. Just MS
being lazy or FS9's inability to be worked the right way. I mean, there aren't too many people that care about some random little airport in the French Alps but CVL has a reputation for being rather different, would have been nice if the runway was the right shape but I'm sure we'll live.
BTW, I hate it when I'm flying in and the FS9 ATC tells me to land on runway 5. Absolutely I'm going to dive about 2 thousand feet, just before the runway and pull up to land in however long the runway is. I'm sure a twotter could do it though.
