I've made a data mod so I can basically make some of the numbers bigger, make morale buildings and asteroid mining more useful etc. I've combined it with Kryo's hull mod, but I'm not sure if that's affecting it at all. I need help with the following:

1. Planetary Improvements come up twice each on the list when I'm adding them to a planet.
2. All my ship designs have disappeared, including the basic ones like colony ship and constructor, though I still have all of my templates.
3. The changes I made to hull HP and weapon/defence numbers don't appear.

I'd also like to know if it's possible and how to change the HP of starbases and whether it's possible at all to make components that add to the HP of a ship when used (mostly to make defences more useful late-game).

I may have just put files in the wrong places, so I'll continue experimenting myself.
