What's New in Mậu Binh Xập Xám
1.0.7
October 24, 2026
Multiplayer stability fixes for rooms with two or more human players: • Fixed games hanging mid-match (e.g. stuck at round 5 of 12). Round timeouts are now processed reliably by the server. • Fixed the round score screen not appearing for the last player to submit. • Fixed "Submit" appearing to take a long time or getting stuck on "Waiting for others…". • Fixed hands being re-dealt after you had already arranged and submitted on round 1. • Submissions with out-of-date cards are now rejected and your hand refreshes automatically so you can arrange again. • Fixed an error when rejoining a room after reconnecting. • Long-idle games are now cleaned up automatically so they no longer block new rooms.
