1. Memory core is now required from ship tier 3.
2. I fixed bugs related to a ship returning to base:
- when a ship was in combat and Return Home was selected, it could get stuck in a movement loop and fly around its last position,
- when a ship was undocked, given the Stop command, then docked again and sent to base, it could remember the previous escort order and refuse to move,
- the mothership would sometimes return to base immediately when a ship was undocked from it during combat.
3. I improved ship positioning in escort formations, so escort ships no longer cluster in front of the commanding ship.
4. The Recycler now starts with 8 command points.
5. I fixed a bug with ship turrets that prevented them from being repaired.
6. A ship commanding an escort, for example a transporter, also gains experience when escort ships destroy enemy units
7. Ships returning to base unload their inventory as well as excess ammunition and fuel.
8. I added an option for deeper terrain drilling while manually mining ore when holding the Shift key.
