4th line form the bottom - if I understand correctly you changed something in rockets.xml. Seeker is probably type of seeking warhead that not exist. All types of warheads must be defined in Rockets.xsd.
I advise you to make a fresh install and start modifying ship from the scratch. Tracking all your previous mistakes may be time consuming.

heres the three files if it would be easier for you to look at what i have done to them ,once again thanks for the help

no thats the weird thing i have only edited the three files that yall said to edit the carcasses.xml shipdescription.xml and quest.xml ive upload them if you could take a look at them

you forgot to place the Liger_Dreadnought.IMD in the appropriate folder? or the Liger_Dreadnought.ini? .ini goes to Data\TEXTURE\Interface\Carcass\Slots
and .imd goes to \Data\OBJECT. Also you don't need to change the quest.xml.

no i did put both files in the right spot ,just double checked ,and sorry i did not edit the quest.xml i edited the quest.script for the mission that gives the mothership from ternie,,so i have no idea what i have done wrong ,

in the carcass file what is the right name to look for to change the 2nd arba you get to the liger,,,,,,,,the clean arba not the pirate version because i think maybe i might have changed the wrong one

Well, my result has been a huge success, ships now happily populate most sectors. Unfortunately, my addition of NESF incursions in seven sectors have not produced the desired results.

I am contemplating attempting to import the spawn and fleet scripts from the Star Wolves 2 mod 'Real SW2'

mothership_arba

pk thanks also what is the mothership_arba name in the ship description file ,not the pirate one but the other one thanks for all the help and understanding

Slightly off topic. I was looking through the XML files today, and found a DynamicMissions.xml. Looks like it's supposed to be replayable random missions that never got implemented.

Edit: I think I have once gotten a random mission to hunt down some pirate, but the game never pointed out where the guy was that I was supposed to kill, and I finished the game without ever completing it.

Just do a search for mothership_arba in the shipdescriptions file...

That is just leftover code from the replayable random missions that were in Starwolves 2. Starwolves 2 had it, but for some bizzare reason they took it out from Starwolves 3. Donno why... perhaps it had some major bugs (i imagine it was probably telling people to go to off-limits sectors) and the developers figured it would be easier to remove completely than to fix.

Look in the same sector you got the mission, you should see a target marker which should indicate where your target is at.
