- Does this mod have any DLC dependencies?
- Extra Ship Components 3.0 does not explicitly require you to have any of DLCs, but some components will not be available unless you have a specific DLC active.

- Does this mod require a new game?
- No, Extra Ship Components 3.0 does not require a new game, though, depending on the game state (particularly, leviathans), some technologies might remain unavailable.

- Can AI use new components?
- Yes. The only thing that might prevent AI from researching Extra Ship Components 3.0 technologies is its own stupidity.

- What about mod compatibility?
- Extra Ship Components 3.0 overwrites 2 vanilla icons to ensure that all components and technologies are distinct. And a UI files for strategic resources. No other vanilla files are changed. And as long vanilla technologies are known to the game, Extra Ship Components 3.0 should work. This is not true for the supplement mod. If you use Universal Resource Patch, make sure that is is locate below Extra Ship Components 3.0 in the list of mods in the launcher, otherwise it will be overwritten.

- This mod adds additional resources. There are no deposits on the map. What is wrong?
- Resources added by Extra Ship Components 3.0 do not have deposits and have to be collected by pops. Living Crystals can also be bought from the galactic market once someone puts any there.
