Question

[Mad Dog]

Does anyone know what it means when:

1. You get a dialoge that says "unit model allready used?
2. When a mission fails to load?

The Unit model thing occurs when you have two aircraft using the same filename in their respective folders. You have different files called the same thing. Usually, it's not fatal to your game, but just annoying.

As with mission failing to load, is this happening at the same time?

If not, missions failing to load often means you don't have all the correct files for a mission to load. -Missing aircraft/facilities/weapons etc.

You get a dialoge that says "unit model allready used?

Building on Flyby's response, one of your aircraft.cfg files is calling the same XDP or M3D file name as another. Or possibly an aircraft.cfg has two versions within it calling the same XDP or M3D. This can occur when you create a new version of an aircraft but you forget to clone and rename one of the M3D files.
