Blades in the Void bug(?)

[DarkAcolyte]

So I'm at the section where the filthy xenos board your ship and try to destroy it by leaving behind a present. My journal tells me to disarm it, and I successfully do so... and nothing happens. My quest log is not updated, leaving the engine room back to the bridge changes nothing, nor does going back to the palace to try and trigger the next part of the quest.

Was there more than 1 bomb? Or did I miss anything else that needed to be done in the engine room? Or am I utterly screwed and need to reload?

I'm not sure if you can miss that, but just in case - you've talked to a surviving crew member, right?
Also bomb defusion requires 2 skill checks, but I doubt that you've missed the second one.

Edit: I've re-did that part, killed Kabalite Sapper without letting him act once (not sure if this affects anything). Interaction with surviving crew member starts automatically, there's only one bomb and after second disarm check (Demolition) quest log immediately updated to "Return to Dargonus". I've approached via alternate route (further along the main corridor there's a narrow path with the broken catwalk which requires you to make Athletics check).

So I'm afraid you've got to reload that part. Maybe verify game files beforehand, just in case.
