The Infinity PDF Collection on Drivethru is missing the current version of the Combined Army. The one in the Collection is V3 but it is V4 in the separate Combined Army product download files if you purchased it separately.
The Coast of Greed Dire Foes PDF is also not in the collection, but is in the Coast of Greed downloads if you got that product separately
Please updated the download files for the Infinity PDF Collection.
