Mount & Blade II: Bannerlord Patch Notes - WS v1.2.6 (11th June 2026)
War Sails v1.2.6 and Bannerlord v1.4.6 are live, addressing several crash bugs that were tanking stability during raids and sieges.
Patch v1.2.6 for War Sails and v1.4.6 for the base game are now live, and this one's all about stability. The big one: that crash when two armies besiege a settlement while you're defending? Gone. Same goes for the crash that hit when starting coastal village raids, a particularly nasty one if you were running War Sails content.
Beyond the crash fixes, there are some quality-of-life tweaks worth noting. The "Leave" option no longer appears when you're trying to help a village under raid, which should cut down on accidental mission abandons. Ship icon inconsistencies on the scoreboard are fixed, and non-shallow draft ships can no longer sneak into naval raid simulations where they don't belong. Radagos' Raider troops were also overtuned and have been brought back in line.
One heads-up: there may be a delay between the base game and War Sails updating. If you launch before both are ready, you'll crash, verify your files if that happens. Here's what changed in detail.
