Heroes of Might and Magic: Olden Era Patch #4: Network (5th May 2026)
Unfrozen drops a targeted hotfix for a multiplayer crash that was killing 3+ player sessions, plus localization fixes across several languages.
Multiplayer sessions with three or more players have been crashing in Heroes of Might and Magic: Olden Era when unit abilities are used during PvP combat, and Unfrozen has moved quickly to address it. Patch #4, out today, is a focused hotfix rather than a sweeping update, but if you've been trying to get a full lobby running with friends, this is the fix you've been waiting for.
Beyond the crash fix, the patch tidies up localization across several languages, including a missing ability description for Temps magique in French, a broken game date display in Japanese, and various typos. Small stuff, but localization polish matters when you're trying to read spell descriptions mid-battle.
Unfrozen also flagged that regional connection issues are still being investigated, and AI balance and game difficulty changes are planned for upcoming patches. For a game still in Early Access, the turnaround on this crash report is decent. Full patch notes below.
