I'm not sure if this is an issue or just my misunderstanding. I thought we were supposed to receive a treasure key per week per character. I usually get one for two of my characters, but the third never seems to get one. If however, you are only suppose to get one period, then never mind, I guess I'm lucky to get an extra. But seriously, only two out of the three ever get a key. It doesn't seem to be any character in particular, but it is irritating.
