Soda Pop Miniatures has announced a misprint in the Von Drakk Manor expansion for Super Dungeon Explore. The box and cards should read 4 Skullbats and Rattle-Bones.
From the announcement:
It has come to our attention that we have a misprint on the VonDrakk packaging and spawning point cards. The correct number of Skullbats and Rattle-Bones you should have are FOUR each. Here are updated cards for both of their spawning points. We apologize for any confusion this may have caused.
