If you have updated your DLC but don't see changes in-game, check your file. X-Plane loads scenery in a specific order; if a custom scenery pack is listed above your Global Scenery, it might be "blocking" the updates from appearing. Always ensure your "Global Airports" and "Global Scenery" are positioned correctly in the configuration file.
It is irresponsible to ignore the elephant in the room. "DLCCodex" historically walks a fine line. Laminar Research is a relatively small team of developers who revolutionized flight simulation.
This is a , not an enhancement patch.
This is different from a “content update.” You are not getting new 3D buildings, improved night lighting, or XP12-style forests.
