Did you pull the databases recently? There have been permission fixes a couple of days ago, since the updates in character database were only able to be applied as user root.

Your mariadb user needs permissions CREATE ROUTINE and ALTER ROUTINE to apply updates...

Bug can be closed.

Looking at commit history, the problem must have been solved years ago.

Tested with current releases of M0-M2, expansion can be set using this command ingame in chat and using mangosd console without any issues.

Your first post indicates that you are using a MangosZero database. Since this bug is published in the MangosTwo section I have to ask:

Are you using MangosTwo with a MangosZero database

or

should this bug be moved to MangosZero?

BTW I cant reproduce this error using MangosTwo with the correct databases.
