Since releasing into Early Access on March 30, Steam-favorite Mount & Blade 2: Bannerlord has had a number of patches. These have largely been aimed at fixing game-crashing bugs, but also updating with small quality-of-life fixes.

Since the April 1 patch, Bannerlord has received three new patches and a hotfix. Patch 1.0.3 was small, with just one fix: "Fixed a critical issue that corrupted save files after a certain number of saves."

April 3’s patch was more extensive, with 17 different causes of game crashes being identified and patched. Patch 1.0.4 also introduced tweaks for increased stability and performance, removed certain debuffs that would hinder the player at night and balanced parts of the campaign.
