Frosthaven Hotfix 0.12.2 Resolves Multiplayer Desyncs and Softlocks

Frosthaven Hotfix 0.12.2 eliminates a multiplayer desync tied to a third player joining sessions. The update also fixes multiple softlocks and card interactions for Trap, Drill, and Deathwalker classes.

Frosthaven receives a targeted hotfix addressing multiplayer stability and card execution errors. The patch eliminates critical desyncs and corrects unintended behavior across multiple character decks and perks.

Multiplayer and Softlock Fixes

The update fixes a multiplayer desync that triggered when a third player joined an ongoing session. Softlocks involving the Trap class using 'Cage_of_Thorns' without valid adjacent hexes and the Drill class taking damage from the Robotic Boltshooter card 'Focus Fire' in Quest 134 ('Tower of Knowledge') have been removed.

Class Card and Perk Adjustments

Boneshaper summons no longer receive double bonus attacks when Banner of Strength activates. The Fist perk 'Sure Footing' now correctly restricts movement lengths, and the Deathwalker card 'Strength of the Abyss' bottom action functions properly as a persistent effect used multiple times. Astral enhancements now apply correctly when using -1, the Shackles perk 'The Accustomed' retains its bonus after phasing to a room, and Meteor card 'Igneous Path' placement adheres to maximum range limits. Finally, the Shackles card 'Delayed Malady' bottom action no longer stacks negative modifiers infinitely.

Why this patch matters

Hotfix 0.12.2 cleans up a wide array of specific character calculation errors and session stability risks, ensuring cleaner tactical play.
