[BUG] Act 4 progression blocked – Hooded One despawned after boss, main quest cannot advance

Hi, I’m posting this on support’s recommendation as I believe I’ve hit a progression-blocking bug in Act 4.

What happened
1. I completed the Solitary Confinement map in Act 4 and killed the boss.
2. After the boss died, The Hooded One spawned with a quest marker above his head.
3. Before speaking to him, I used a portal to return to town to sell items.
4. When I returned to Solitary Confinement:
• The Hooded One was gone
• The boss loot was gone
• The instance remained fully cleared (no enemies)

Current state
• The main quest does not progress
• I do not receive the next quest involving the ship / captain
• The quest tracker appears stuck and I cannot advance the campaign

What I’ve already tried
• Forcing a new instance (Ctrl-clicking the zone)
• Replaying the entire Solitary Confinement map and killing the boss again
• Logging out completely and re-entering
• Checking all town NPCs for new dialogue
• Restarting the game client

None of these resolved the issue.

Expected result

Speaking to The Hooded One (or re-triggering the encounter) should advance the main quest and unlock the next area.

Actual result

The Hooded One does not reappear and the campaign cannot progress.

I’ve seen older posts describing similar behaviour when portaling out before speaking to The Hooded One, so this may be a quest-state desync.

Happy to provide any additional info if needed. Thanks for looking into this — it’s currently blocking all further progression on this character.
