War Thunder Update v2.57.1.103 Fixes Critical Server Desync

War Thunder update v2.57.1.103 eliminates a severe server-client desynchronization issue that broke repairs, missile guidance, and radar locking. Active Premium Accounts and specific event progress have also been extended by 24 hours.

A critical server-client desynchronization bug in War Thunder has been resolved with patch v2.57.1.103. The issue caused widespread failures across ground and naval combat, preventing basic mechanics like repairs, radar locking, and weapon deployment. Affected players receive compensatory time added to their accounts.

Critical Desync and Combat Fixes

Patch v2.57.1.103 addresses a major desynchronization error between clients and servers that crippled core gameplay loops. The fix restores standard functionality for repairing ground vehicles and ships, missile guidance systems, radar target locking, and bomb bay doors. Hit registration problems on naval vessels and target following errors in marker-based modes are also resolved. Collision calculations that allowed ground vehicles to pass through each other have been corrected. In Nuclear Escalation content, a bug blocking players from spawning into the B-52H aircraft has been fixed.

Player Compensation

To account for downtime and disrupted matches caused by the desynchronization issue, active Premium Accounts have been extended by 24 hours. The progress requirement for Mark of distinction for sailors 4 during the Guardian of the Baltic Sea event has also been extended by a full day.

Why this patch matters

This emergency update repairs game-breaking combat bugs that affected War Thunder. The 24-hour account and event extensions provide compensation for the disruption.
