The report previously I reported is in my own miss.
However, I revealed that for the plot, two prisoners should be freed, but there could be an undefined behavior depending the player position.
1. Go to the prison.
2. Regardless of the prison outage, just go to ZYA Chimera directly.
3. Upboard the ship, and the trigger is skipped. However, in the objective screen in the map, the window still says
I should free the prisoners.
This can potentially confuse some users. Even, two prisons are too dark to see them directly, I had passed one prisoner
