Lina froze the whole Upper Hadar

[Gatts]

Well - I had technical problem in the same location - but quite different [while I was "pulling" the lever in locked dialogue chain - I was also attacked by enemy stack and game frozen]

For your problem - I would advise to attach here your save game + your game version and wait till the devs will look at the save game - this looks like typical "tech support needed" issue.
