All the bugs reported for missing buildings have been fixed - at least those reported on this forum and to us
via e-mail or facebook. The reason for all of them were either SODE not installed / activated or SimConnect not installed.
In most cases re-running the SODE installer fixed the problem. In the other cases the SimConnect installer.
A few customers also had outdated SODE versions where in fact SODE objects weren't found due to case sensitive naming convention.
But I haven't received any reports so far except for yours about a problem within the XML itself. In fact, if you check the XML you will see that
both files are exactly the same except for the season definition which differs between Default and FTX Global Prepar3D.
I own 30+ airports all using SODE so you can rest assured SODE is installed, activated and up to the very last version released, that is 1.6.3. Simconnect is installed too, well at least I hope so after 20 years in simming.
But no worries, I can live with default textures. I just don’t quite get it why you still use SODE for seasonal textures. Controlling textures with SODE was very popular with devs but it fell out of favour, not least due to issues like this, a long time ago.
