[0.4.0] Atlas progression blocked – Fortress boss not spawning after Return to Zorin

Version: 0.4.0

Issue:
After entering the Atlas and killing Rysch (quest boss), the quest updates to "Completed – Return to Zorin".
However, when speaking to Zorin, the quest does not properly conclude and no further dialogue or completion trigger occurs.

As a result, Fortress / Stronghold bosses never spawn in the Atlas, completely blocking Atlas progression.

What I have tried:
- Relogging / restarting the game
- Re-entering the Atlas
- Killing Rysch again
- Running many Atlas maps
None of these resolve the issue.

Current state:
- Quest shows as completed and instructs to return to Zorin
- Zorin does not finalize the quest
- Fortress bosses do not appear at all

This appears to be a progression-blocking bug introduced in 0.4.0.

Expected behavior:
After returning to Zorin, the quest should fully complete and unlock Fortress boss spawns in the Atlas.

Thank you.
