i tried again and it work now. first i clear data and restart new game. then i played without mod on until i can send adventurer to world map for collecting items. and then i emptied my gems to speed expedition and send expedition again and try to speed things up. and shop for gems button is appear. then i go to gems section, turn on free purchase mod on and buy some gems. then cancel payment and purchase gems is success.
thats it. thanks for the mod for this game
