I think game have a write protection because I edited expirience level value +1000, but when gamee add points after an event, value = old value + events point only.

Level experience address 0x205B72B3450
7FF6ECFE0FFA - 8B 86 400A0000 - mov eax,[rsi+00000A40] <<


Functions that access just before & after game modify Level experience address .

Is it possible bypass protection or is server-side?

Thanks so much in advance
