As a side comment partially related to your bug, I see by your screenshot that there is still generic traffic. This is a line from 1.5.1.0, the first beta version:
I’ve tested quickly with “Real-Time Online” and “AI offline” traffic type and a empty Community folder.
With “Real-time online” traffic, I wasn’t able to reproduce. Unfortunately, I’m unable to check if this issue happened with Aircraft Trafic type set to “AI offline” traffic as none is injected. Certainly related to this other bug-logged AI OFFLINE traffic disabled, trafficAircraft.bgl is empty - #39 by C0rsten
Unrealistic with everything. I put in 12000 ft and atc says 7100. And im flying west ifr. And STILL assigns a runway opposite the wind direction. STILL. unless the wind sock is wrong. AGAIN. which is possible . AGAIN. lol
Although the absolutely stupid flight level changes may be attributable to 3rd party products, I should point out that, despite recent improvements, I still get the original problem with ATC - i.e. moderately stupid flight level change requests. Ten miles out from Stansted in a C172 on IFR, ATC requested me to ascend to FL190.
