I was able to spent it but i was getting the occasional error after attempting to buy more gumballs, & when the error came up i had to reload the game and re edit the value again.
Editing the value to show in-game to what i chose to edit it to was working but sometimes it gave me a error after a couple of purchased attempts, To fix that i just had to begin from cheat engine again.
It wasnt stable to mod those values because the game would give you a error at any moment after editing the value but sometimes the error wont occur until a couple of purchased attempts allowing me to abuse it as many times as i wanted until the game gave me a error.
I didnt release the location of the LD in cheat engine for others to try because it wasnt a stable mod to do and after 30 minutes i did get banned.
You needed to edit the LD value on the menu screen not on the LD 3 machines screen. By editing the value at the menu screen carried your value to the machine screen.By editing the value at the machine screen would not update your value of LD in-game and would break your LD until you restart the game.
The most LD people can hold is 2147483647 > When that number goes to 2147483648 they will go into negative and will have to earn 2147483649 to go positive to 1 LD again .
although i did get banned fast it was fun to mess with it.
