Sephiria Patch 1.0.29 Hotfix

Why 1.0.29 exists

Patch 1.0.29 shipped on 2026-08-14 as a targeted multiplayer fix for Sephiria (app 2436940) on Steam. TEAM HORAY added the 1.0.29 fix to the existing 1.0.28 hotfix announcement — the installed Steam build identifies as build 24734903. Install the newest client to get both fixes cumulatively.

This is not a content expansion. Sephiria stays six chapters, Steam Windows and macOS, online co-op up to four, and no host migration.

The Chapter 6 multiplayer freeze

The core fix addresses a bug where progress could occasionally freeze after a game over in Chapter 6 multiplayer environments. If a player died during the finale and the session was waiting for a respawn or vote to continue, the lobby could stall — forcing a host migration that does not exist, or leaving all four players stuck on a black screen.

This was a timing and state-sync edge case, not a guaranteed repro. Players who completed Chapter 6 multiplayer runs without dying, or who ran with two players instead of four, were less likely to hit it. However, the freeze was severe enough to warrant a hotfix between the earlier 1.0.26/1.0.27 feature pass and the upcoming 1.0.30.

Relation to 1.0.28

1.0.29 does not replace 1.0.28 — it adds a fifth fix on top of the four already in that patch:

Fix	1.0.28	1.0.29
Chapter 4 story-object UI	✓	✓
Weapon tooltip keyword bleed	✓	✓
Hard Mode difficulty on gamepad	✓	✓
Time-change function reset	✓	✓
Chapter 6 multiplayer freeze	—	✓

Install the newest Steam client to receive all five fixes.

Update checklist

1. Steam → Sephiria → confirm news shows 1.0.29 (2026-08-14).
2. One full four-player Chapter 6 run — die once intentionally and confirm the lobby continues cleanly.
3. No other gameplay changes require re-testing.
4. Then read 1.0.30 for the latest content additions (new BGM, Frozen Bow arrows, language additions).
