I've encountered a weird bug on my last flight from KDEN to KSLC.  I set up my route as I would any US domestic route in any FMC-equipped aircraft while on VATSIM - select the SID and STAR, but do not select runways until assigned.  At Denver, I selected the Rockies 9 departure RLG transition, direct EKR transition to the SPANE5 arrival.  I did not specify landing north or landing south at this stage.  This is when I activated, then executed, the planned route.  I then completed the perf init and called tower for my clearance.  I entered my runway, ignored a weird glitch where the aircraft route went DCT DEN DCT ZIMMR (which is incorrect since this is a radar vectors departure in mountainous terrrain).

During my climb, I noticed that KSLC, about an hour away, had no local controllers online.  My weather engine suggested that the preferred configuration at this field was south, so I went to select the ILS 16L, then returned to my legs page to check the altitude restrictions against my charts.

The IAP failed to insert, the entire STAR had been deleted, and when I went to my route page, the destination airport had been changed from KSLC to KDEN.  This affected the Progress page as well as all functions related to VNAV.

This is a bug that must be resolved as soon as possible, as it affects anyone flying online, especially those flying outside the US and Canada where all SIDs and STARs are assigned by ATC.

If it's at all related, I fly exclusively in the VC; I only use the 2D cockpit when lag makes the VC unusable (which I have not experienced on the CS 757).
