Description:

Solo mission / Story Chapter 1: Tales of the Past / Ancient Tower:
The signal ( ExplPrison ) does not work, there is no explosion of the cryochamber.
The signal ( ExplosiveBolts ) does not work, the wall in the entry room does not explode.

Steps to Reproduce:
1) No explosion of the cryochamber takes place after the dialog with the prisoner.
2) I return back to the entry room, go to the red wall and nothing happens, it is not possible to get out of the ancient tower.

 

Yes, after the message 'run' there was no explosion and I could talk to the prisoner.
No, I did not use my drone.

 

Unfortunately, I had already disabled the mission manually and went on with the story.
In the HUD on the right side was the state (TaskTitle - Close Escape) and (ActionTitle - RUN!)

I've tried this chapter of the story twice and the result is the same.

 

If you talk to the prisoner without entering his room, the mission dialog advances to "Close Escape, RUN," but the explosion does not go off. (I think that sometimes I have seen it advance to "Check the walls" also.) If you walk into the prisoner's room before speaking to him, it works properly.

 

Basically I walk up to the cell door until it says press F to open, and then walk toward the prisoner until it says press F to talk to him. You end up standing outside the cell.

Yes, you can come back, enter the room, and talk to him, and it will arm the explosion. (I think that when I tried before, I entered the cell but did not speak to him again (since I had already spoken to him).)
