Because it's a bit hard to see what's happening here..
1. a gravity field is placed (yellow thing) to get freighter2 to turn towards his station
2. freighter2 turns, and another gravity field is placed
3. an anti-gravity field is placed (orange thing) to prevent freighter3 from turning
(violet things are planets, asteroids,.. that have gravity same as gravity fields)
4. since i didn't manage to remove the antigravity field for freighter2, he keeps turning...
5. freighter 3 reaches his station and is done
5. I switched the camera to freighter2 (bottom buttons)
6. the gravity field at freighter1 gets removed so he's just moving straight ahead again
7. pirate fires at freighter1, freighter 1 jumps through wormhole, and I removed the gravity field at
freighter2
8. switched camera to freighter1
9. wormhole destroys itself
10. switched camera to freighter2 and placed anti-gravity field on solid
11. freighter 1 has reached his station
12. freighter 2 reached his station and the mission is completed successfully.
13. YEY!
