This is a weird case of it works on everybody's machine, except mine. This is less of a project issue, but a dylib injection issue, as no dylib injector works, i'll admit that. I had dylib injection working, and one day, it just broke. I'm not sure if I changed a setting and not noticed but it ain't working anymore.
