the galaxy manifest is NOT used in entrenchment 1.02 also there are 5 map groups to cycle through, ie small,medium,large, map designer, and galaxy forge.
all of the maps in the galaxyforge folder show up in the galaxy forge map group all of the maps created with the map designer are stored in the map designer folder and show up in the map designer group
I agree that a folder under my documents\my games would have been easier to find and use, BUT this is what ironclad chose
hope this helps
