Frosthaven Hotfix Clears Up Multiplayer Attack Modifiers and Freezes

A targeted Frosthaven hotfix addresses multiplayer sync issues for ambiguity options and stops freezing during mind-control turns. It also restores missing Update 3 challenges for older campaigns.

A new hotfix for Frosthaven addresses several frustrating technical roadblocks, most notably tackling campaign progression bugs and multiplayer desyncs tied to optional rules.

Multiplayer and Stability Fixes

Campaign Progression

Players running older campaigns should now see Update 3 challenges appearing properly, correcting an issue that left legacy save files locked out of intended content.

Why this patch matters

This quick patch resolves key stability blockers for cooperative play and legacy save continuity, making multiplayer sessions much more reliable.
