i have both Ireland and Japan download but for some reason i could't play japan if i also have ireland download and vise versa. Then i try to look the game file and i found out that Japan and Ireland uses the same IDs beetween 15000 and 15055 for the custom items and quest line. And beacuse Japan have less custom items and quest line. If you "ASEL" could change Japans IDs so i dont need to delete and download every time want to play one of the maps. I love both of the map and i want to have both of them.
