Panatreea Potion Vendor
From Creatures Wikia
Sometimes the Potion Vendor does not install. To install the Paratreea Potion Vendor 3.0 you need to place panavend.agents in your My Agents folder (for Creatures 3 and Docking Station), often located in: C:\Program Files\Gameware Development\Creatures Exodus\[Game name]\My Agents\
NB. After the game has been run next, if it produces any catalogue-related errors you might need to check that all the catalogue files are in the C:\Program Files\Gameware Development\Creatures Exodus\[Game name]\Catalogue\ directory as well as in the My Documents one, and that you have run the Creatures Remastered Patch.
