Game version
Due to the frequentcy of the questions, I will record the current game version of Bannerlord required to play Bannerlord Online. This should at all times be the latest stable version of Bannerlord, so never the beta branch!
Current version:
v1.2.12.54620Version release date:
December 2, 2024Native Issues
Not all problems you encounter in Bannerlord Online are actually caused by the mod. So if you experience unusual issues not listed in any of the errors below, have a look at the Taleworlds known issues thread.
