Thanks by the tip, many times I forger that most of the soase files are text.
About the 4 ability, for me it is more a solution than a problem, I was thinking about no more of 3 abilities at capital ships. When I added 4, it as at a tyrant missile cruiser and it was more for test a few features, I want use it as a missile cruiser with interdictor capabilities.
About other features, I was thinking about the Death Star, I want add it as the normal Galactic Empire Titan, it is perfect because it can be builded only one at same time. But.........I would like know if I can change the model with different upgrades as the starbase, I want start with the Death Star prototipe, next the death star I and after it the death star II.
