Another ILS Intercept Bug

[Fechulo]

While testing v3 at KORD, I noticed that aircraft were failing to intercept the ILS. However, in the current version of the game, aircraft can easily intercept the ILS at that distance and altitude:

v3

v2

Acording to the charts, aircraft should be at 2,200ft at SIBLY:

So the aircraft should be able to capture the glideslope, since it is at 2,000ft and it's supposed to join the localizer ~1nm before SIBLY
