Agreed. I think developers do tend to practice "co-opetition" and thus communicate when they can and when they think it's appropriate. And I figured Jarrad would've known that Gianni was working on this and, while that didn't stop JustSim, I'm surprised Jarrad moved ahead. But who knows what, if anything, was going on behind the scenes.
But yeah, it does get a bit annoying when developers double- or triple-team on certain airports or areas meanwhile when others are totally neglected. I'm with ya on that.
