why do i only see the 3DO data package in "downloads" and not the Urquan Masters game package?

I did have QM installed in early december, but i removed it, and now i cannot find it in the package manager to reinstall it.

if i open the package manager and go to downloads/games i see only the 3DO package
if i open the package manager and go to uninstall i can confirm the game is not still installed

any help appreciated
