When I am loading mission 2 (not including training missions) of the campaign, this came up during loading.



Error: Invalid ship class name.

In sexpression: ( when
   ( has-departed-delay 2 "Unknown NTF" )
   ( send-message
      "#Command"
      "High"
      "Warp Out"
   )

I initially thought it crashed, but it turned out that I could still run the mission, but just as the Iceni jumped out, I get this error

Error: Ship class "NTF Iceni" invalid

The mission ends, then I get this error

I am highly confused -_-

Edit: I my build is 3.6.8 with the corresponding .exe...

You've installed Derelict incorrectly haven't you?

   
I'm playing a mission but instead of the ship I'm expecting I just get a Ulysses fighter.

This is the result of installing a mod that alters the ships table. Although it can occur for any missing ship it is most noticeable when the affected ship is supposed to be a giant capship. The game goes to the ships table expecting to find a certain type of ship but can't find it cause the mod has replaced or removed that ship from the ships.tbl. When FS2 can't find a ship on the table it replaces it with the first ship on the table which in most cases is a Ulysses.

Basically if you're using FSO you should follow the instructions here when installing mods.

I tried it, but now when I try rerunning the mission, I get the same error.

Hmmm. Something is overriding the tables in the media VPs. We need to figure out what.

1. You should have no files in your main FS2 folder that aren't in this picture (Extra folders are fine, as is anything ending in .avi).



2. Run FS2_Open but click on no mod from the launcher. Do you get the error?

3. Now run the campaign again and select your mediavps folder as the mod. Do you get the error now?

If not we're done. If so tell me when you got the error.

Sometimes, in my case, i've even had to create a new pilot in order to make it work when my tables get mixed up. Specially working with MODS on SCP.

It's worth a try with some problems but I really doubt this is a pilot error. The game is reporting that it is unable to find a ship on the table it is using. Which basically indicates that the wrong table is being used.
