When I inject my cheat using LoadLibrary, it works fine, using Manual Map I get an exception:

Code:
Exception thrown at 0x00000000 in csgo.exe: 0xC0000005: Access violation executing location 0x00000000.
DLL Entrypoint:

Code:
BOOL WINAPI DllMain(
    _In_      HINSTANCE hinstDll,
    _In_      DWORD     fdwReason,
    _In_opt_  LPVOID    lpvReserved
)
{
    switch(fdwReason) {
        case DLL_PROCESS_ATTACH:
		{
			MessageBox(HWND_DESKTOP, "b1g pasta fatboy loaded", "ayyyy", MB_OK);
			CreateThread(nullptr, 0, OnDllAttach, hinstDll, 0, nullptr);
			return TRUE;
		}
        case DLL_PROCESS_DETACH:
            if(lpvReserved == nullptr)
                return OnDllDetach();
            return TRUE;
        default:
            return TRUE;
    }
}
Crashes with Extreme Injector as well as my private injector, haven't tested any other injectors.
