Hi,

I alloc memory with

Code:

alloc(gOTable,$512)

then later I try to load an address in an AOB injection

Code:

lea r14,[rcx+10]
lea r13,[gOTable+0*8] <-- this is just 0 for testing but supposed to be rbx
mov [gOTable],r13
mov [gOTable+8],gOTable

when I register goTable and check

[gOTable] and [gOTable+8] they both contain

721159442 -> 2AFC0512

When I try to use

Code:

mov [gOTable],1 - everything works no problem
mov [r13],1 - crashes the game instantly

Code:

rbx = 1;

lea r13,[rbx*8]
mov [gOTable+8],r13

works and [gOTable+8] = 8

lea r13,[rbx*8]
mov [gOTable+r13],r13

crashes

I'd really appreciate help.

EDIT:

so apparently after some testing it seems as Cheat Engine is not adding the module base to it as soon as you do non static math.
