• Resolved: Desync error #304 that occurred when two players built a market at the exact same gametick.
• Added: A 3-second delay before a player can resign, preventing accidental "rage quits" from registering as game disconnections.
• Updated: LAN lobby refresh rate. The game now properly detects all games on a subnet without requiring a direct IP entry.

While it never became a household name, Castle Strike developed a cult following thanks to its intricate castle building, resource chain management, and large-scale battles. However, like many ambitious titles from the early 2000s, it shipped with a host of bugs, multiplayer instability, balancing issues, and performance problems on then-new Windows XP systems.
