Frosthaven Patch 0.12.2 Fixes Crashes, Desyncs, and Softlocks

Frosthaven's latest hotfix targets stability issues, addressing multiplayer desyncs tied to the undo feature, quest-breaking softlocks, and audio errors.

The newest hotfix for Frosthaven tackles critical stability problems, including game-breaking softlocks, audio-triggered errors, and multiplayer desyncs. Patch 0.12.2 also resolves multiple quest progression blockers and errant character card interactions.

Stability and Multiplayer Desyncs

The update eliminates an error triggered when music starts playing during a Quest or at the Outpost. Multiple desync causes have been resolved, including those linked to using the undo feature generally and specifically during round 1 of Quest 31 "Cracking Tunnel".

Quest-Breaking Bugs and Softlocks

A softlock that occurred when a monster died from Bane while a Boneshaper had the "Soul Claim" top action active is fixed. In Quest 86 "Lady In White", a bug causing crashes when attempting to kill the Lady In White has been resolved. Additionally, the Steel Automaton in Quest 134 "Tower of Knowledge" now correctly spawns once all four pressure plates are activated, and characters can properly move to the Spirit Realm from an adjacent Altar during movement abilities in Quest 38 "The Way Forward".

Character and Card Adjustments

Several class mechanics and card interactions now function as intended. The Boneshaper perk "Reclaimed Essense" can be skipped during long rests, and activating the Banner of Strength no longer doubles the damage of the Bone dagger summons bonus. For the Geminate, players can no longer reuse the top action of "Scarab Flight" by undoing a second push prompt. The Trap card "Improvised Improvement" can now place traps on hexes occupied by flying enemies. Finally, modifying movement via an element consumption card in Quest 108 "Lustrous Pit" no longer locks movement fully, and pillars in Quest 110 "Guardians Temple" now display a destruction animation.

Why this patch matters

Patch 0.12.2 is an essential maintenance drop that removes frustrating roadblocks and multiplayer instability, making ongoing campaigns much smoother.
