Help/Support Problem with patching function

[DiveMaster 304 6]

In game I am trying to modify there is function like this 

// RVA: 0x16DFC3C Offset: 0x16DFC3C VA: 0x16DFC3C
	public static void SpentStuds(long studCount, long newTotal, string resourceFlowId, eTransactionType transactionType) { }

I tried to patch its arguments and even putting just solo RET to not let it do anything but game still manages to get it to work while I confirmed the function is being called when studs are changed. What I am doing wrong? There is no other function that handles that transaction.

is the game server sided or client sided? That may give you the answer as the why it wont work.
