The cabalcash tool is uses hard-coded values for the server idx and duration so you have to edit manually or wait for newer gm tools.
After adding the items using the cabalcash tool run the following query on the cabalcash database:
Code:
update mycashitem set serveridx=1 where serveridx=24
I'm sure if you check the "mycashitem" column titles you can figure out how to change the command to do the durationidx too but you should do the durationidx first as it needs changing before you grab the item in the game.
