I'm in the same boat - my copy of the expansion was missing three of the purple mythological creature meeples. The cafegames.com website no longer seems to exist. Does anyone have current contact information for a North American source that I can contact in order to obtain the three missing pieces? Feel free to send a Private Message if you'd rather not post an email address in a public formum.
Edit: Looks like I have the lead I was looking for, the place to contact is www.asmodee-us.com
