Okay, then I guess it could be LittleNavMap as that uses Sim connect. I have it refresh every 500 ms. Perhaps I can have it refresh every second or longer and see what happens then. I also use ActiveSky Evolution, but I used that before and never had this issue. So it must be LittleNavMap. I see this building problem at KLAX and PHNL as well.
Speaking of Las Vegas. I could have sworn that the Janet terminal had JNT or JAN parking designators, Well, none of my Janet aircraft park at the terminal because there is no parking spot designator. I can't edit the AFCAD since BGLcomp isn't working for me in ADE, which is another problem I have to get sorted.
