# In multisession mode = 2, the command of connecting account->character (@ic <charactername>) seems to be invoking MuxCommand, but, at the point of its execution, the character's attributes aren't initialized, so my at_post_cmd reference to caller.db.hp doesn't exist. It's a NoneType, not an Int. Maybe? Also, commands that use account, like who, also throw the same way.
