Diamond value changes back after increasing with GG

[Warutsu]

Hello, I tried to increse the value of my Diamonds in Love Nikki and it was easy to find the value (I'm a noob), but after changing it it changes back to what I had (246). 
It says to choose a value between -1,8e+308 and 1,8e+308 if thats helpful.

Those are controlled by the games servers.  Game guardian may be able to change the VISUAL number. But the actual number will be the same,  and as soon as the game refreshes with the servers,  the value will return to the actual number.  Freezing this value won't help,  because again. That real value is all controlled by the game servers.  Which can not be hacked
