No bug, works as intended. This is what it says when you select your main:
Select this character as your main character - that will allow this one (and only this one) to participate as a Hero in Strategus, play as a Mercenary in Strategus Battles, trade with other main characters and do other funky stuff. This is irreversible. If you want to change to a new char, you will have to delete this one and create a new main character from scratch!
